What's the story of the New Year's Day quiz?

Tujia people have an emperor who likes to guess riddles. This New Year's Day, he heard that Bocica of Tujia nationality was proficient in charades, so he called him and three other people into the palace. The local tyrant asked Bocica to make a riddle, and the other three people guessed it. Bocica immediately made a gesture: pointing up, pointing down, pointing left, pointing right, pointing forward, pointing back, then patting his chest, sticking out three fingers and spreading his hands.

The first guess is the county magistrate. He said: "I am the county magistrate of Qipin, in charge of benefiting the people, the third class on the left and the sixth room on the right. I am in charge of Five Blessingg for three days! " Wu followed suit and guessed, "Snow covers the top, old trees cover the bottom, left flowers are arranged, right flowers are arranged, and bows and arrows are behind. I am a martial arts expert, and the lucky star shines high for three days! " Finally, when he arrived at the division of Yin and Yang, he guessed: "I know astronomy above, geography below, Zuo Qinglong, right white tiger, former Suzaku, and later Xuanwu. I am a teacher of yin and yang, and I have a good fortune in three days! " Pocahontas said coldly: "You are so smart that you can't guess any of them!"

Seeing that the three guessing experts couldn't guess, the local tyrants wanted to know the answer, so they asked Bocica to answer it. Pochika glanced at the local tyrant and said, "Heaven never shuts one door but the earth never shuts another. We Tujia people are in a dilemma. We poor people can't lift the pot cover for three days. You only say promotion, wealth, beer and skittles. Where is your conscience? ! "
