What does the legend of Meng Jiangnu crying down the Great Wall show?

The legend of Meng Jiangnu crying down the Great Wall illustrates the following two points:

1, the cruel corvee system in feudal society can only bring miserable life and miserable fate to ordinary people.

2, the embodiment of the tyranny of the Qin Dynasty, the cruelty of the labor system of the Qin Dynasty.

Meng Jiangnv's Mourning for the Past is one of the four great folk love stories in China. The legend of Meng Jiangnv crying at the foot of the Great Wall in Wan Li, northern Hebei Province, has been circulated among the people for thousands of years. According to legend, when Qin Shihuang built the Great Wall, his work was very heavy. Fan Xiliang, a young man and woman, married Meng Jiangnu for three days, and the groom was forced to start building the Great Wall. Soon, he died of hunger, cold and fatigue, and his bones were buried under the Great Wall. Meng Jiangnv wore a warm coat and went through a lot of hardships. Wan Li came to the Great Wall to look for her husband, only to get the bad news of her husband's death. She cried at the city gate for seven days and seven nights. This section of the Great Wall collapsed, revealing Fan Xiliang's body. Meng Jiangnu buried Fan Xiliang in despair and threw herself into the sea.
