Personally, I think patents are the most transparent.
You can search on the official website of China National Intellectual Property Administration. The website is free. You can use it as long as you register. Generally, there is a Chinese abstract translation.
Personally, it is more likely to be false. China's design patents will not be examined in substance, but will be authorized after formal examination. Foreign estimates are similar. Of course, it does not rule out the review opinions.
Find it yourself.
good luck
