Footprints, photos, socks?

Footprints, I know, are the most famous ones, which we Baidu know. Footprints have traveled all over the world and are famous enough.

As for the existence of this trademark, we need to inquire, but from the perspective of Baidu's protection of intellectual property rights, the owner of this trademark should belong to Baidu (I think so), but there are many profit-seeking people in the market, and it is very common to make fakes, don't you think?

You'd better take a picture. This is the most convenient solution.
