Gambling during Tet holiday (bài bạc ngày tết), also known as Lunar New Year, is a deeply ingrained tradition in Vietnam. This annual practice involves families and friends gathering together to play a variety of games, including bau cua ca cop (a type of dice game), li xi (red envelope giving), and xoc dia (a spinning game). Despite its popularity, gambling during Tet holiday is also a controversial topic, with some people arguing that it perpetuates negative social behaviors and values.

The roots of Tet holiday gambling can be traced back to ancient times when gambling was considered an essential part of the celebration. According to legend, during the reign of the Hung Kings (approximately 2879-258 BC), people would gather to play a game called "li xi" as a way to bring luck and prosperity to their families. The game involved throwing six coins and depending on the number of heads or tails, the player would win a prize.

Gambling during Tet holiday also has cultural significance. It is believed that playing games during this time can help build strong relationships among family members and friends. In Vietnamese culture, the act of gambling is seen as a way to share joy and happiness with loved ones, and winning or losing is not the main focus. It is the act of participating and bonding that is important.

However, gambling during Tet holiday is not without its critics. Some argue that the practice promotes greed, addiction, and irresponsible spending. Others argue that it perpetuates negative social behaviors and values, such as cheating and dishonesty. In recent years, the Vietnamese government has attempted to regulate gambling during Tet holiday, with mixed results.

Overall, gambling during Tet holiday in Vietnam is a complex and multifaceted tradition with deep historical and cultural roots. While it remains a popular practice among many Vietnamese people, it is important to consider the potential social and ethical implications of such activities. As the country continues to modernize and evolve, the role of gambling during Tet holiday is likely to continue to be debated and evaluated by both scholars and the public.
