When is it good to open an east gate to the east of the factory wall?

In Tiananmen Square, according to our local custom, we should first look at the orientation of the house, then choose the year of this orientation in Italy, and then choose different months, dates and hours according to the birth years of all male landlords.

There is also an inviolable principle: don't be the east gate in spring, the south gate in summer, the west gate in autumn and the north gate in winter. After the date is chosen, the relevant ceremony can be held.
