This matter still has to start from Liu Bang's youth. At that time, Liu Bang was a local ruffian, but he didn't like working in the fields. Even though he was repeatedly reprimanded by his father for being inferior to his brother, Liu Bang still went his own way, idled around every day, had no income, and liked to make all kinds of "friends". This family is really angry, but it's hard to say anything, especially Liu Bang's sister-in-law.
Since then, Liu Bang has often invited friends to his home. Only his sister-in-law can cook, but she really doesn't like Liu Bang and complains to her husband every time. But as Liu Bang's brother, he just comforted his wife. After all, he still cares about his brother. This also caused her sister-in-law to spend more and more time tolerating Liu Bang who did nothing but eat, until one day, Liu Bang's brother died.
Now, how can eldest sister-in-law let Liu Bang come to dinner? When Liu Bang and his friends came over, Sister-in-law said that there was not enough cooking at home today, which means that the soup was finished. Over time, Liu Bang also felt strange, so he went to the kitchen to open the lid and found that the pot was full of rice.
This time Liu Banglai was angry. I didn't expect my sister-in-law to show such disrespect to him. After Liu Bang proclaimed himself emperor, he sealed the official positions of all his relatives. Only Liu Bang, the son of his sister-in-law, made soup for him, that is, scraped the bottom of the pot with a spoon. This is a satire on his mother.
