This contract shall come into effect as of the date of signature by both parties. Party B's name or position is not filled in on the first page. As long as it does not affect the understanding of the parties to the contract, there is no problem in legal effect. Just fill in Party B's name or position. It is suggested that when signing a contract, if there are two pages, both pages should be signed and stamped with a sewing stamp to avoid the contents of the first page or other unsigned contracts being modified by the other party without authorization, and disputes will be very troublesome.
