The Vietnamese word "tang chứng" is a noun that means "evidence" or "proof." It refers to something that can be used to show that something is true or to support a claim.
"Luật sư đã thu thập tất cả các tang chứng cần thiết để bào chữa cho thân chủ của mình."
(The lawyer gathered all the necessary evidence to defend his client.)
"Các nhà khoa học cần tang chứng để chứng minh giả thuyết của họ."
(Scientists need evidence to prove their hypothesis.)
In a legal context, "tang chứng" can refer not only to physical evidence (like documents or items) but also to testimonies or expert opinions that can support a case.
While "tang chứng" primarily refers to evidence in a legal or factual context, it can also be used more broadly in academic or scientific discussions to refer to data or information that supports a conclusion.
