The Vietnamese word "buôn lậu" refers to the act of smuggling, which means to illegally transport goods across borders without paying taxes or following regulations. It can involve various types of goods, including drugs, weapons, or stolen items.
In a more complex sentence, you might say: - "Chính phủ đã áp dụng nhiều biện pháp để ngăn chặn tình trạng buôn lậu." (The government has implemented many measures to prevent smuggling.)
While "buôn lậu" primarily refers to smuggling, it can also imply dishonesty or unethical behavior in a broader context, especially when discussing illegal activities.
