When Venus met Su Kui, she welcomed her daughter-in-law not to have children.

Literally, this sentence should be easy to understand.

When Venus travels to Quezon, if you marry a wife, you won't have a son/child. In other words, it is not suitable for marriage.

Two concepts that need to be explained are "He" and "Su Kui":

In astronomy, sum means that two celestial bodies are equal in longitude, so we can roughly understand that Venus is closest to Quezon (in fact, there is always a considerable distance between them).

Let's talk about Quezon. It is one of the 28 constellations, located in the west of Andromeda and northeast of Pisces. A * * * consists of sixteen stars, of which Milac is the second largest star (Andromeda β), and the famous Andromeda galaxy is located slightly northeast of Quezon X.

Ancient Chinese astronomy divided the celestial sphere into 28 pieces along the celestial equator like watermelon, and named each piece after the nearby stars. When some celestial bodies fall into corresponding positions, there is a specific occupational system to predict the corresponding good or bad luck. But I can assure you that this set of things must have arisen among the people after the late Qing Dynasty, because it is a standard symbol and has always been regarded as a taboo by the imperial power.
