May 9th is a good time to hang a plaque.

The premise is: if we don't care about the character of the shopkeeper or whether one day is good or bad for the shopkeeper, then let's call it May 9, and I'll tell you:

1. According to the Book of Auspicious Selections, 3: 00 to 5: 00 is the auspicious time for Qinglong. When setting off firecrackers, it is good to point them in any direction.

2. It's also auspicious if you choose 2 o'clock to 7 o'clock. When it's the hall, firecrackers should go south.

3, 1 1 point to 13 is also auspicious. When it is golden, set off firecrackers to the northwest.

Give advice, you can choose. But I still suggest that the host has a specific eight characters, and it is the most accurate to choose the five elements of Ji Shi through the eight characters.
