There is only one fit and taboo in the yellow calendar: what do you mean by not trading this for something else?

Yu, the same as "Yu". There are "easy" days and "taboo" days in the yellow calendar. You should not do anything except what the yellow calendar allows (such as seeking medical advice, treating diseases and demolishing houses ...).

It can be translated into modern Chinese: "Nothing else can be done or done". Don't take anything else, that is, don't do anything else, which is second only to other things.

The extended materials in the daily almanac include "Yi" and "Taboo". "Appropriate" refers to things suitable for doing, such as bathing, getting married, treating diseases and demolishing houses. "Taboo" refers to things that are not suitable for doing, such as avoiding praying for blessings, opening markets, breaking ground, and burying.

Instead of taking the rest, this means that on this day, except for the things stipulated in the Gregorian calendar, the rest are not suitable for doing. If it is appropriate to seek medical advice, treat diseases and demolish houses, then anything other than these things is not suitable, which can be translated into modern Chinese: "Nothing else can be done or done."

Don't take anything else, that is, don't do anything else, which is second only to other things.

"Pave the road, don't rest": a geomantic term. Paving the road is paving the road, which is the same as the explanation of the road. Don't take the rest, don't do anything else. The whole meaning is that you can only do things like leveling roads and nothing else on this day. Otherwise, you will break taboos and you will not succeed.
