Legal subjectivity:

The power of attorney must be signed by the person to be valid. A power of attorney is an expression of the will of both parties. In principle, it requires the signature of the trustee to express recognition of the entrustment. Once signed, the entrustment becomes effective. When entrusting others to exercise their legitimate rights and interests on their behalf, the entruster must produce the entruster's legal documents when exercising their rights. Legal objectivity:

Article 62 of the "Civil Procedure Law of the People's Republic of China" When entrusting another person to litigate on your behalf, a power of attorney signed or sealed by the client must be submitted to the People's Court. The power of attorney must clearly indicate the entrusted matters and authority. An agent ad litem must have special authorization from the client to admit, waive, change claims, conduct settlement, file counterclaims or appeals on his behalf. The power of attorney sent or entrusted by citizens of the People's Republic of China living abroad must be certified by the embassy or consulate of the People's Republic of China in that country; if there is no embassy or consulate, it must be certified by the embassy or consulate of the People's Republic of China in that country. The certificate must be certified by the embassy or consulate of a third country with which the People's Republic of China has diplomatic relations in that country, and then certified by the embassy or consulate of the People's Republic of China in that third country, or by a local patriotic overseas Chinese group.
