Legal analysis: Yes, the receipt is not stamped. If there is no signature or fingerprint, it generally has no legal effect. In law, a receipt without an official seal is not recognized, so the receipt must be stamped with the official seal or the signature of the party concerned. Therefore, if the receipt is issued by a company or unit, it generally has no legal effect without the official seal, but if the receipt is signed by the legal representative of the company, it is regarded as having the same effect as the official seal.

Legal basis: Civil Code of People's Republic of China (PRC).
