According to the verification, there is a point in the character-exploring seal script. The original meaning of this word is to explore from the hand, and to explore from the cave with branches. However, the word "acupoint" was originally a little bit, but it has not been developed so far. Why did you cancel this point? There is no way to test it. According to my estimation, this point was originally included in the treasure cover, and it was omitted for simplicity in the development of fonts. If so, please correct me.
