　　Hello, everyone. Today, I will explain a basic course of chess and cards-the detailed explanation of the basic card type of chess and cards.with BL777 Casino Login For example, if it continues to develop, it will definitely become the benchmark of the industry and play an important role in leading the market. https://www.bl77777.com/

　　First of all, why explain this course?

　　First, 80% of chess and cards are composed of the following 10 basic types of cards. If you master these basic types of cards, you will have mastered its basic laws.

　　Second, many players only know about dragons, heavenly roads and one-on-one fights. But I don’t know what double jump, pat company, one room, two halls, one hall and two rooms are, not to mention sticking to these roads every time, every time, every time!

　　Third, I have heard at least thousands of players who have lost and still don’t know what a basic card road is, such as one room, two halls, one hall and two rooms.

　　Therefore, I will popularize the basic knowledge of chess and cards for you today.

　　As shown in the figure, the results of each game of chess and cards are usually displayed in the following five ways, namely, Zhupan Road, Dalu Road, Dayan Road, Xiaoyan Road and Xiaoqiang Road, among which Xiaoqiang Road is called Luozha Road in Guangdong. Each boot card consists of 8 decks of playing cards. Generally speaking, according to the thickness of cutting cards, the normal chess AG is about 70 games, while the Myanmar chess AG is about 40 games. Next: Let me explain the first card type: Changzhuang. That is what we often call Zhuanglong. As shown by the red circle on the main road, when there are four or more villages in a row on the main road, it becomes a long village.

　　Changzhuang

　　The second card type: Long Idle, which is indicated by a blue circle in the road, is called Long Idle or Idle Dragon when there are four or more idles in succession.

　　Changxian

　　The third card type: pat the stork. This word is pronounced like a stork, but we are used to calling it row by row. The definition of row-by-row connection is: when there are two or more rows of villages adjacent to the road, this combination appears twice or more, which is called patting and sticking. figure 1

　　Pat snipe

　　Figure 2

　　Pat snipe

　　The fourth card type: single jump on the road. What I want to point out here is that not every time a village appears, it can be simply called a single jump on the road. What is jumping? For example, it is 6 o’clock in this office and 6 o’clock or more in the next office. Its amplitude exceeds one cycle, and it must appear four times or more in one office before it can be called a single jump. Everyone must remember this! As shown in Zhupan Road, Idle 6 goes to Zhuang 9, and then Idle 9 Zhuang 8. During this period, their amplitudes all exceed one period, which is obviously a single jump on the road!

　　Mahjong, as a time-honored traditional chess game, has attracted countless players with its rich gameplay and profound cultural heritage. If you are new to mahjong, you may find the rules and terms of this game complicated and dazzling, but rest assured! This article will provide you with one-stop mahjong introductory teaching, so that you can easily master the basic knowledge and get started quickly. This is not only learning, but also the beginning of fun.Even so, B1777 link We must also adhere to the quality of the industry and create unique products for the company. https://www.bl77777.com/

　　The charm of mahjong lies in its various ways of playing. The basic types of mahjong cards can be divided into three types: ten thousand characters, barrel characters and strip characters! Specifically, there are 36 swastikas from 10,000 to 90,000; There are also 1 to 9 strips, a total of 36; Like the name, there are 36 drum plates from one drum to nine drums, plus four wind plates and three plates, and finally there are 136 in total. The combination of these cards adds endless possibilities to the game.

　　Next, let’s look at the basic operation of mahjong. At the beginning of the game, the dice will be rolled to determine the direction of the dealer and the seat. Shuffling is not a problem. Remember, right in front of the whole mahjong table is the opposite home, the upper home on the left and the lower home on the right. Each player touches the cards in order, starting with the dealer, 14 cards will be touched, and the leisure family will touch 13 cards. Everyone is eagerly waiting for the first card to appear!

　　How to roll the dice? When we roll the dice, the number of points added by the two dice determines the position of holding the cards, and the smaller dice will tell you where to start holding the cards. Simple, right? After touching the cards, it is the dealer’s turn to play the first card, and then each player touches the cards and plays cards in turn. Remember, you have to take a new card from the pile after the leverage!

　　Playing card type analysis is also the key to getting started with mahjong. There are several main card types that should be paid special attention to: a straight is three cards with the same suit in numerical order, an engraving is three identical cards, and a pair only needs two identical cards. More complicated ones, such as bar cards (four cards are the same) and uniform cards (the whole deck is composed of the same suit), have their own characteristics and are colorful, which makes the world of mahjong so charming.

　　In mahjong, the rules of eating, touching and bumping are also very important. You can only eat one’s cards when you eat, but you can touch three when you touch them, while the bars are divided into open bars and dark bars. These skills are tips for winning in the game. As long as you make good use of them, you will definitely become a mahjong master.

　　How to play Hu cards is also a rule that novice players need to be familiar with. When the cards you catch are combined into a draw, it’s self-touching. And shooting refers to playing the cards needed by the other three. This means that the whole game is full of strategic and psychological contests, which is really unexpected and exciting.

　　If you are curious about mahjong and want to find out, follow our steps, learn our skills and start your mahjong trip! Whether it’s gathering with friends or family reunion, this game can make you laugh and cultivate your feelings. Why not? Through this article, please enjoy this contest between intelligence and luck. I believe you will find your own fun and highlights in this traditional culture.

Mainly includes poker, landlords, China chess, military chess, gobang, mahjong and so on.from BL777 Casino Login From the reference value, it can also bring a lot of inspiration to other industries. https://www.bl77777.com/

　　Chess and card games can be divided into poker, landlord fighting, mahjong, China chess, Go and military chess. It can be said that the richness of chess and card games is completely beyond your imagination.

　　In China, Landlord Fighting, Mahjong and China Chess can be said to be the most well-known players. After all, China Chess can be said to be the quintessence of China, and Landlord Fighting Mahjong has become omniscient among the people. People over three years old basically know these chess games, so today we will talk about the unknown contents of these chess games.

　　Dou dizhu, a popular Chinese poker; fighting the landlord

　　Nowadays, most of the landlord fighting industries rely on online. Since the first full game of JJ Landlord Fighting was held online, the offline card game has not been adopted, and now online landlords are in full bloom. Online landlords have occupied half of the landlord fighting world, while offline landlords have struggled to survive in the residual wind of online landlords. With the outbreak of the epidemic in the past 20 years, online landlords have developed to a kind of existence beyond the peak.

　　Nowadays, online landlord fighting, JJ landlord fighting and happy landlord fighting still occupy more than 80% of the market, while other games such as Zen Tour Landlord Fighting and National Landlord Fighting occupy 20% of the market. Although these games occupy 20% of the market, their market share is getting less and less under the oppression of JJ landlord fighting and happy landlord fighting. At this time, a new landlord fighting game is needed to enter the market, just like the catfish effect, to activate the vitality of landlord fighting.

　　mahjong

　　In today’s mahjong industry, online and offline still coexist, and there is no bias to which side. In this case, Tencent Happy Mahjong used to rank first in the market. However, Fingertip Sichuan Mahjong has sprung up this year, and its promotion under various platforms is in full swing, and various benefits have been promoted one after another. In terms of promotion, it has seized the pain points and ideas of users on various platforms and further deepened the influence of Fingertip Sichuan Mahjong.

　　Compared with Tencent Happy Mahjong and Fingertip Sichuan Mahjong, they have gradually formed a balanced state. At this time, a game is needed to break their balance and push the mahjong game to another peak.

　　Xiangqi

　　Perhaps many people haven’t played China Chess online, and they are basically entertaining offline, but now online chess is developing more and more rapidly. With the development of software such as China Chess, Chess, Boya China Chess, and chess masters, and the promotion of last year’s epidemic, online chess is also like a light wheel of time, struggling forward.

　　Chess offline is far more exciting and interesting than online games, but times are changing and chess will gradually change.

　　In the chess game, listening to cards is a skill, and listening to cards is a craft. Listening to cards means that you are about to enter the stage of Hu cards, which means that the final victory will not be too far away. Generally, players on the field basically start to listen to cards at the later stage of the game. At this time, whoever listens well and can master the skills of listening to cards will win the game earlier. Today, the new recruitment game will come to say for everyone?So, BL777 On the contrary, there is still a lot of room to play. https://www.bl77777.com/

　　1. Listen to multiple cards-in a card type, players usually choose to listen to several cards. For example, 2,345,000, and the cards drawn at this time are 20,000 and 50,000. If it’s 2,345,600, then the draw cards are 10,000, 40,000 and 70,000. However, players need to pay attention to the fact that if some of the cards in Hu are likely to destroy the overall card type, such as one-stop, flat Hu and so on.

　　2. Listening is monotonous-it means that when players listen to cards, they just listen to a single card and want to make a pair.

　　3. Listen to the hole-for a simple example, if the cards in the player’s hand are 20,000 or 40,000, then the card type that the player listens to at this time is 30,000 holes.

　　4. Listen to the side card-listening to the side card is similar to listening to the hole. For example, at this time, the cards in the player’s hand are 70,000 and 80,000, so the card type that the player listens to at this time is 90,000.

　　5. Listen right-if there are two pairs in the player’s hand, at this time, you only need to make another set of engravings, and the other set will be used as a card. In this case, the player needs to listen to two cards, and this card drawing type is called listening right.

　　When listening to cards, players must pay attention to the card type of their family, and try not to listen to the same card type as their family, so as not to be called Hu by their family in advance. If your last family happens to be the dealer of the game in this bureau, it’s like avoiding listening to the same cards as your last family. If you can hide, you can hide!

　　Laser cleaning technology is a revolutionary advancement in cleaning methods, offering high energy density, precision, and efficient laser conduction. It has clear advantages over traditional cleaning techniques, enhancing cleaning efficiency, accuracy, and targeting specific areas. Moreover, laser cleaning avoids the environmental pollution caused by chemical cleaning processes and does not damage the underlying material.Only by working together can we turn laser cutter The value of the play out, the development of the supply market needs. http://laserscheme.com/

　　Principle of Laser Cleaning

　　What is Laser Cleaning?

　　Laser cleaning is the process of removing materials from solid (or sometimes liquid) surfaces by irradiating them with a laser beam.

　　Low laser flux: The material absorbs laser energy and evaporates or sublimates.

　　High laser flux: The material converts into plasma.

　　Most laser cleaning uses pulsed lasers, but continuous wave lasers can also ablate materials. Factors like laser wavelength, pulse length, and material properties affect the ablation rate, while laser scanning speed and coverage further influence the process.

　　Types of Laser Cleaning Technology

　　Laser Dry Cleaning:

　　Pulsed laser irradiates the surface, causing either the contaminants or the substrate to absorb energy and expand, resulting in separation.

　　Laser Wet Cleaning:

　　A liquid film is applied to the surface. When irradiated by the laser, the liquid vaporizes, generating a shock wave that removes contaminants.

　　Laser Plasma Shock Wave Cleaning:

　　Laser irradiation generates a plasma shock wave, which releases energy that removes contaminants without damaging the substrate. This method cleans particles as small as nanometers.

　　Physical Principles of Plasma Cleaning

　　Absorption: The contamination layer absorbs laser energy.

　　Plasma Formation: A rapidly expanding plasma generates shock waves.

　　Contaminant Removal: Shock waves break contaminants into fragments.

　　Controlled Energy: Laser pulse width must prevent heat accumulation to avoid surface damage.

　　Applications of Laser Cleaning Technology

　　Semiconductor Field

　　Used for cleaning semiconductor wafers and optical substrates, laser wet cleaning and laser plasma shock wave cleaning are commonly applied to remove particulate pollutants without damaging the substrate.

　　Metal Material Field

　　Laser cleaning is highly effective in removing oxides, rust, paint, and coatings from metal surfaces. Applications include pre-welding cleaning and aircraft skin maintenance. The process is efficient, non-damaging, and has seen wide use in various industries.

　　Development and Expansion of Laser Cleaning Technology

　　Laser cleaning technology has advanced significantly, with applications now in aerospace, military, and electronics fields. The technology has been maturely applied in paint and rust removal, and recent innovations have enabled cleaning oxide layers from metal wires. With continued development, laser cleaning will likely expand into new fields, and fully automated systems could be achieved by integrating with industrial robots.

　　Future Trends in Laser Cleaning Technology

　　Strengthening Theoretical Research:

　　Further research is needed to establish a comprehensive theoretical system to guide laser cleaning applications.

　　Expanding Applications:

　　The expansion of laser cleaning into new fields will drive its development, supported by innovations in equipment.

　　Development of New Equipment:

　　New laser cleaning systems will feature both versatile and specialized designs. The integration of industrial robots is a key trend in fully automated laser cleaning.
