What do you mean by "Ping Zhi Dao Tu"

Laying roads and other fortifications.

Pingding Daotu is a term used by China people for a long time in the Yellow Calendar. Pingzhi means rectification. The so-called paving is to build roads.

In the Gregorian calendar, it belongs to the category of appropriate words, that is, the day of the ecliptic is marked as "flat road", so this day is suitable for road construction. In the Gregorian calendar, this item is often used with "don't take the rest of the things", which together means "don't take the rest of the things", indicating that nothing is suitable except road construction that day.
