I happen to be familiar with this aspect. Here's the thing. If you register a trademark, you usually find an agency and need to provide a company license or a personal license. Trademark application is a one-time payment, and an official fee of 1 0,000 yuan needs to be paid to the Trademark Office. If you entrust an agency to handle it for you, it will cost you several hundred yuan. If you are not familiar with this aspect, you can look for "Zheng Bo Standard Network" in Baidu, which is a relatively large trademark knowledge platform.
