When reading this question, many individuals will visualize the 'neck' and 'mouth' of humans or animals. Typically, these two parts coexist simultaneously on a single entity, so no one can think of the answer. However, persisting in that direction will never yield the correct response.
The answer is presented extremely simply, known and possessed by everyone. That is: The shirt.
On a typical shirt, there are components like: Sleeve, hem, collar... however, there is no part called 'shirt mouth'. And that is the accurate answer to this perplexing question.
Indeed, in Vietnamese, there are numerous words used with various meanings, but users are only familiar with common, characteristic meanings. There have been numerous occasions when this type of question perplexed many individuals. Such as the question: What creature is alive but does not die?

The answer may seem difficult, but it's actually a knife, something present in every household. Because on a knife, there is a part called the 'knife edge'. The knife edge is the thick edge of the knife, contrasting with the blade. And there is no part called 'dead knife' on it.
Hence, to 'battle' all Vietnamese riddles successfully, users must possess quick thinking and an extremely vast knowledge.
