The Vietnamese word "tệ đoan" is a noun that refers to social evils or corrupt practices in society. It is often used to describe behaviors or actions that are harmful, immoral, or detrimental to the community or social order.
"tệ đoan" is commonly used in discussions about social issues, ethics, and governance. You can use it when talking about problems in your community or issues in politics.
In more advanced discussions, "tệ đoan" can be used to analyze specific issues within a society, such as: - "Chúng ta cần phải đấu tranh chống lại các tệ đoan xã hội."
(We need to fight against social evils.)
While "tệ đoan" primarily refers to social evils, in a broader sense, it can sometimes refer to any negative characteristic of a practice or behavior, though this is less common.
