What's the name of the river demon?

In the original book, Lian Huaqing appeared holding Lian Qiuniang's leg when she entered the door. At that time, many people thought it was a child born of Lian Qiuniang's adultery. Even Qiu Niang was anxious at that time. Even the family thought the child was their home, and they didn't want to drive Lian Huaqing out, so they named him.

Many people say that the empress went out to visit relatives and crossed the Yongding River by ferry. The ferry capsized and fell into the Yongding River, killing all the people on board. She was the only one who escaped and got pregnant when she got home. The child must have been reborn as a river demon, so even Huaqing was called a river demon.

The original book also said: When Lian Huaqing was still living in Lian Mansion, a fortune teller passed by Chen Tangzhuang, and all the people who looked for this fortune teller were correct. Even the master invited a fortune teller to see Lian Huaqing's children. When the fortune teller saw Lian Huaqing, he saw the child's vertical stripes, and his eyes were full of longing. He only said that he was short-lived. Otherwise, people would rather smash the signboard.

Later, Lian Huaqing was kicked out by his uncle and had to wander outside. But then even the house caught fire, and it was suspected that even Hua Qing's hand was below. It can be said that Lian Huaqing's setting in the original work is very bad. As for whether Lian Huaqing's background in TV series has changed, Bian Xiao is not sure.
