Legal analysis: Although you can sometimes sign other names, such as other people's names, it should be noted that the owner of the name must be authorized, otherwise the act is suspected of "forgery". Although the validity of a contract does not always depend on whether it matches the name on the ID card, the signer must take it seriously and not harm the interests of others, such as signing other people's names and pseudonyms.
