Bai doi thuong, often referred to as Tai Xiu or Tai Buquinh in Vietnam, is one of the most widely played traditional games in the country. Originating from China, this card game has been adapted to Vietnamese culture and has become a beloved pastime for people of all ages. The game involves players competing to collect points by matching their cards with those of other players. The goal is to win rounds by being the first to reach a certain number of points or to have the highest score at the end of the game. Tai Xiu is played with a deck of 54 cards, divided into four suits: Phai (circles), Giao (swords), Co (hearts), and Tinh (diamonds). Each suit has 13 cards, including one King, Jack, Queen, Ace, and numbered cards from 2 to 10. The game begins with players dealing cards in a specific order, often starting with the dealer or host. Players then take turns matching their cards with those of other participants. The rules are complex, requiring both knowledge of card combinations and strategic thinking to win. One of the most exciting aspects of Tai Xiu is the use of "Phao" (Bullets), which are wildcards that can substitute for any card. These add a layer of unpredictability to the game, making it more challenging and entertaining. Over time, the popularity of Tai Xiu has grown significantly in Vietnam. It has become a cultural symbol, often associated with intelligence, quick thinking, and social interaction. Families and friends gather around to play, while tournaments are held in various venues across the country. The game's appeal lies not only in its strategic elements but also in its ability to bring people together. Whether you're a seasoned player or new to the game, Tai Xiu offers an exciting and rewarding experience that continues to captivate audiences.
