The place where the word "seal" is printed on the power of attorney is stamped or stamped next to it, usually in the lower right corner of the power of attorney, and some are directly below it, not necessarily. Be careful not to cover up important information when stamping.

The power of attorney is valid as long as it is the true signature or seal of the client. However, in practice, especially when dealing with important matters, in order to avoid trouble (such as the cost of clearly authorizing facts), it is best to use notarization authorization, so that the trustee can handle the entrusted matters more conveniently and smoothly.
