I have reviewed the second complete set of RMB of National Securities before. To be fair, the control is relatively strict. It uses the internationally recognized Sheldon 70-level numerical rating standard. It is not easy to give ratings. Among domestic rating companies The National Securities Rating (GSNG) is good. It promises permanent authenticity and guarantees compensation if it is fake. At least it will not confuse the fake with the real one. The score given can also be called a conscience. Their main source of income does not rely on appraisals and ratings, so they do not accept orders with bad products that want to be rated high, and they do not earn the money that affects their reputation. Therefore, they are more fair and only rate orders that meet their standards.
