China's well-known trademarks are administratively recognized by the State Administration for Industry and Commerce or by the people's courts at or above the intermediate level. Generally, companies do not dare to pretend to be China's well-known trademarks. And often those who claim to be "China's famous brands" or "China's famous and high-quality products" are certificates issued by some so-called associations or fictitious organizations.

Well-known trademarks recognized by the State Administration for Industry and Commerce can generally be found on the China Trademark Network, and can also be queried on the websites of provincial industrial and commercial bureaus. However, there is no unified channel for querying well-known trademarks recognized by the courts. Some provincial industrial and commercial bureau websites also list judicially recognized well-known trademarks for query.

In fact, there is a saying that goes well: a gold cup or a silver cup is not as good as the reputation of the common people. It is more trustworthy to ask around customers who have used it.
