For example, in the gossip the day after tomorrow, Wu is a hurdle and Yin is a Kun, which describes people as beautifully dressed, but in fact they are kind and calm. In addition, Yin Na is also closely related to the longevity of the Chinese zodiac, such as the gold in Wujiasha and the golden bath at noon.
