Does the health certificate business license need to be stamped?

Legal analysis: if the company needs to apply for a health certificate, it needs to prove: a copy of the company's business license (with official seal), a letter of introduction from the company, a labor contract, a copy of my ID card, and two one-inch photos.

Legal basis: Regulations on Hygiene Management in Public Places.

Article 5 The competent department of public places shall establish a health management system, equip full-time or part-time health management personnel, regularly check the health status of their business units (including individual operators, the same below), and provide necessary conditions.

Article 6 A business unit shall be responsible for the hygiene management of the public places it operates, establish a hygiene responsibility system, and conduct hygiene knowledge training and assessment for employees.
