Excuse me, is there a sect of Yin and Yang Gossip? Only Taoism has gossip about Yin and Yang?

The question you asked is not correct. Yin and Yang are just an abstract concept and theory. There are two kinds of gossip, one is Fuxi gossip, and the other is Wang Wen gossip. The former is also called innate gossip, and the latter is also called gossip the day after tomorrow. The difference between them is in the field of geomantic omen and divination. Taoism uses the name "Taiji Eight Diagrams", and the names of Yin and Yang Eight Diagrams are rare, at least I have never heard of them. In addition, it is taboo to hang gossip in Buddhist temples. I mean, what's the point of doing this? Although there is a period of integration of Buddhism and Taoism in history, it is two kinds of beliefs after all, and this difference is fundamental. Therefore, it is best not to have a conflict of beliefs in religious places. Besides, it's unnecessary. What is the use of hanging eight diagrams in Buddhist temples?
