Excuse me, barristers, should individual industrial and commercial households stamp the position of legal person or natural person on the contract? There are only two signatures on the contract: the legal person and the natural person. There is no legal difference, because the self-employed do not have the legal person qualification in law, so it doesn't matter whether you stamp or sign in the legal person position or the natural person position. If you are Party A (Party B), you only need to stamp on Party A (Party B).
