The language in which the contract is signed does not affect the legal effect of the contract. If it can be proved that the English name is himself, it will not affect the validity of the contract for him.

In order to ensure that the above-mentioned certificates can be obtained, it is often required to indicate in the power of attorney that "the signature of the agent is shown below (right)" for comparison when necessary. The signature of the legal representative of the enterprise may be filed in the administrative department for industry and commerce. Private activities often require handprints.

An extreme example is that drawing a circle is a signature.
