The cap wasn't purchased, but obtained overseas, when Cheng Yan used to participate in racing competitions to earn money. Occasionally, some races would distribute these types of merchandise to the contestants, better ones would give racing suits, and many would hand out caps like this or canvas bags.
Usually, the competition's LOGO would be printed on them. Although they weren't worth much, these items were typically not available for purchase.

This cap had also become a discontinued model, by rights, there shouldn't be many in the country.
Bo Jingshen remembered he owned one, but for the moment, he couldn't recall where he had put his cap.
And the one that man wore looked strikingly familiar.
