What was the original name of Liu Che, the Emperor of the Han Dynasty?

1) Legend has it that the pig is the predecessor of the emperor, that is, the predecessor of the dragon, and Emperor Wu of the Han Dynasty began to call it Queer.

2) Liu Che, the former name of Emperor Wu of the Han Dynasty was Herry Liu, because there was Li Ji walking sideways in the harem of Emperor Wu of the Han Dynasty Liu Qi. His mother, Wang Yi, was afraid that her son would be too conspicuous and become the target of Li Ji, so she called him son, which means little pig.

In the Wei and Jin Dynasties, the book The Legend of Emperor Wu of the Han Dynasty explained this way:

It is said that Emperor Han Jingdi dreamed of a red-haired pig during his nap at Chongfang Pavilion one day. Later, Yao Weng, who gave him divination, interpreted his dream and said that a great man would be born in this pavilion, which was the master of the prosperous times of the Han family. So Emperor Jingdi changed the Chongfang Pavilion into a temple and ordered the king to live here. On the seventh day of July in the first year of Yuan Dynasty (BC 156), Wang gave birth to a son, who was named Herry Liu after his dream. When his son grew up, he was officially called Liu Che.

However, most historians of later generations think this statement is absurd, and Li Zhensheng, a contemporary scholar, thinks that Jingdi gave his son such a name out of kindness.
