What does it mean to open the meridian loom in Geng Wu?

"The loom on the meridian of Gengri is empty, and the master will not cover it in the afternoon" is a divination formula from Yu Sagger, which means don't knit on Gengri, or you will be busy in vain; Don't build a roof at noon, or it will be easy to change owners.

This formula expresses a divination prophecy that Geng Day and noon are not suitable for spinning and building houses. This is because these activities need to consume a lot of energy and time, and if they are not appropriate, they may lead to half the effort and even bluff.

It should be noted that this is only a divination, and there is no scientific basis. In real life, we don't have to be overly superstitious, and we need to arrange our production and life plans reasonably according to the actual situation.
