It means hoarding rare goods and waiting for high prices to sell them.
It is also a metaphor for taking something special or exclusive as capital and waiting for opportunities to gain fame and fortune.
Zi Chu is the grandson of the son of the King of Qin. Zi Chu's mother, The Last Month Of Summer, was not favored by the Guo Jun family, while Zi Chu was in the middle of more than 20 sons of the Guo Jun family. He is not the eldest son, so his position is very low. Lv Buwei was already a wealthy businessman, and he was very good at speculation. When he saw Zi Chu, he felt that he was like a precious commodity, and he could gain fame and fortune by him in the future. Lv Buwei knows the inside story of Qin very well. Knowing that Mrs Huayang was Ann's favorite, but had no son, she made up her mind to let Mrs Huayang accept her stepson Chu as her adopted son. Then, after Prince Ann Guo Jun ascended the throne, Zi Chu will be a prince, and she will certainly make countless money by using special political capital.
Lv Buwei showed his eloquence, saying that Chu was clever, knowledgeable, made friends all over the world and ambitious. Although he is in a foreign land, he misses the kind and virtuous Mrs. Huayang every day, and sometimes he even misses crying late at night. Mrs. Huayang was moved by his words and had a good impression on Chu. Mrs Huayang used Guo Junren's love to persuade him to make Zi Chu his heir.
After the incident, Zi Chu's situation and status changed greatly: Ann Guo Jun and Mrs. Huayang gave Zi Chu enough money and asked Lv Buwei to be his teacher to help Zi Chu. Since then, Lv Buwei has lived in Handan for a long time, making friends with Zichu, waiting for the day when he returns to China to be a prince, and preparing to inherit the throne in the future.
Six years later, in 2 15 BC, Zhao Haoqi of Qin died, and Ann Guo Jun acceded to the throne. This is King Xiaowen of Qin, Queen Huayang and Wang Zizi Chu. Ann Guo Jun's reign was very short. She mourned for her father for one year, and died only three days after she officially acceded to the throne. Zi Chu acceded to the throne, is the king of Qin Zhuang. Just after he acceded to the throne, he made Lv Buwei the prime minister, and he was also appointed as the prime minister.
After Ying Zheng became the king of Qin, Lv Buwei became more powerful. Moreover, he also won the title of "Guanzhong". He is famous for his food and thousands of children, and his wealth is huge. At the same time, in order to expand his influence, he gathered many public figures and asked them to collect historical materials, and finally compiled Lv Chunqiu ~
