Yes, because this is a duty behavior, but if the company does not admit that this person exists, how can you prove that this person is the personnel manager of the company and he has the right to sign? You are in trouble. For example, Nantong Morita Fire Equipment Co., Ltd. is like this. When he arrived at the labor bureau, he refused to admit that the signer was its vice president of personnel. Lying in broad daylight, cheating you, dragging you down. It is better to choose more than one between legal person and official seal.
