What does Meng Jiangnu mean by crying for the Great Wall?

Then Meng Jiangnu cried that the catkins of the Great Wall had been hit by the wind. It is not surprising that crows gather together, so beware of being bullied at home. When you go backwards, you will see good luck. If you can improve, you will be worried. The poem says: this meaning has been predicted, and no one dares to deceive the sky. Gan Kun is tall and stout, so he naturally doesn't doubt himself. Home: Your breath comes from the ground for no reason, just because there is sorrow at home. Pray for God's blessing as soon as you come back, and the house will not be affected now. Everyone in Bujizhai should be patient, so as to prevent right and wrong, and Master Byford should be safe. And there is a disaster, the child will cry all night. If you are happy, you can change the word "Zhang Men". If the kitchen is not prosperous, it is beneficial to repair the well, but it is useless to thank the land god. Migration: I have been afraid of him for a long time, but I can't wait for my fate. If migration is the same, it is better to stay away from the forest. The migration is not smooth, and the boat is tired. Zushan: Bu Guizu is auspicious, and Qinglong's back is blocked. If it is favorable to repair the well, the financial tripod will be prosperous. Cao Jing: There are knots here, but this is not your blessing. Because it is an obstacle, people who are hindered will not be allowed to do what they do. I hope not to fight hard, so as not to lose money. Yang Ji: Buyang House should be built to avoid losing money. Don't take it, Ji. The handwriting on the door of the old house is not good-looking. If it is beneficial, it will be repaired, and if you live there, it will be safe. For academic work, it may be very difficult at first, and you will encounter setbacks and failures, but you will make a breakthrough through hard work. Remember not to give up easily.
