Legal analysis: In general, as long as the handwriting is neat, a signature that can be recognized by the public is ok. Whether it has a specific legal effect generally has little to do with the form of signature, but mainly depends on whether the contract signing subject signs it himself, and the signature will not take effect until the real intention is made.

Legal basis: Article 143 of the Civil Law of People's Republic of China (PRC) is valid for civil juristic acts that meet the following conditions: (1) The actor has corresponding capacity for civil conduct; (2) the meaning is true; (three) does not violate the mandatory provisions of laws and administrative regulations, and does not violate public order and good customs.
