What does it mean that there is spider essence in the fortune-telling garden?

This is the ancient fortune teller's view on how many sons a person has in his life. The specific viewpoints are birth month versus birth time, ugly time in the first month, Yin Shi in February, Three Lunatone Spears, Chen Shi in April, Shi Si in May, noon in June, late July, application in August, Youshi in September, Qiushi in October, Shihai in November and Zishi in December. Fortune-telling calls a person's birth month and time the Zodiac, and this state is the last one of the Zodiac, called the Nourishing Palace. The fortune teller said, "Of the three sons in the palace, only one can be saved." It is said that the garden palace is the life of raising a palace. I can have two daughters and a son in my life. The two daughters are married, and it is not good to cry. The daughter-in-law married by the son is happy. Why is this? The fortune teller said it was because of the garden palace where Zi Xi lived. There is a spider elf weaving a web. Luo internet bar is only allowed to fly in, and it is absolutely impossible to fly out. If you marry a woman, you will fly away, even if you marry a son-in-law. Therefore, it is best not to marry a daughter, but to adopt a son-in-law and be happy to have a child with you ... The fortune teller thinks that people with spider spirits in the garden are selfless and selfish, selflessly raising their children, but selfishly unwilling to let them fly away. The final outcome of this kind of life will be changed, just like the garden will encounter a storm and the spider web will be broken, so when he dies, there is only one child left.
