Hello, I would like to ask what kind of stalk chicken feet are? Black chicken feet are used to describe black powder. At first, "Aikun (the name of KUN fans)" was used to satirize the black powder mixed into their fans. Once it is not covered up, it will be called a small sunspot, which is mostly used to describe black powder. However, due to the second creation of netizens, "Little Black Spots" have evolved again. Everyone will pretend to be "Aikun (the name of KUN fans)", and then suddenly turn around and hack his brother. Then the netizen will comment below that "the little black spots show their chicken feet".
