How do public comments clear all comments?

Unable to clear. "Public comment" means that as long as businesses from various industries settle in this software, they need to accept the evaluation of various users. These evaluations will help others to understand the specific quality of each business, and there is no function to clean up the evaluation in this software, so the evaluation cannot be cleaned up. Public comment is a leading local life information and trading platform, and it is also a consumption sharing platform focusing on local life, eating, drinking and having fun, helping everyone explore and discover the wonderful inside and outside the city.
