Time promised by annual officials

Five days after the Great Cold Festival, 10, starting from beginning of spring Day, is the time for the senior officials to make a promise.

Emperor Qianlong of the Qing Dynasty once convened a group of university students who were familiar with astronomical calendars and the five elements of Yin and Yang, and compiled a book "Explaining Ji Bian's House" to guide official and folk affairs. There is such a sentence in the section of "Reform of Building and Burial Rights" in the book: "On the vertical construction of houses, the demolition of houses began the day after the fifth day of the Great Cold, and beginning of spring completed the vertical construction the day before, so it is not taboo to open a mountain to Keshan Family and Niansha, which is called the handover of old officials."

Five days after the Great Cold Festival and 10 days after the beginning of spring Festival, those who want to rebuild their old houses should not be afraid of being fierce.
