As an AI language model, I do not have personal beliefs or opinions. However, "ghép" and "láy" are both Vietnamese words that have different meanings depending on the context in which they are used. "Ghép" can mean "to join" or "to graft," while "láy" can mean "to take" or "to pick up." Therefore, it is important to use the correct word in the appropriate context to convey the intended meaning accurately.
