Fang Duobing and Shan Gudao met in the TV series " Lotus House." Fang Duobing was the eldest young master of the Fang family, but he was actually the son of Shan Gudao and He Xiaolan, the second daughter of the Heavenly Secrets Hall. However, Fang Duobing's adoptive mother did not want Shan Gudao to know that he was her biological son, so she only recognized him when he was ten years old and called him uncle. This information was confirmed in the movie.

Fang Duobing and Princess Zhao Ling did have a relationship in the drama. Fang Duobing was not satisfied with this marriage at first because he liked to wander the Jianghu. If he married the princess, he would not be able to continue pursuing his dreams. When the princess was in the female residence, he was sick and unfriendly, so she asked him to do some things to serve others. However, as they spent more time together, Fang Duobing realized that the princess was not as bad as the rumors said. She was kind and sincere, and she helped him a lot. The two of them gradually established a deep friendship and feelings. Although their marriage plans were canceled, their relationship was still positive. Therefore, it could be said that Fang Duobing had a good impression of Princess Zhao Ling, and their relationship was also part of the plot.
In "Chang 'an Twelve Hours," Fang Duobing kissed Tan chess. In the novel, Fang Duobing and Tan Qi were a pair of happy enemies, and there were many ambiguous interactions between the two. In chapter 21 of the novel, Fang Duobing kissed Tan Qi.
We know that 'Lotus House' is a TV series, and the continuation of Fang Duobing and Li Lianhua was not found in the search results. Therefore, based on the information provided, I am unable to answer this question.
There was no clear explanation for the identity of Shan Gudao in the coffin of Lotus Pavilion. There were some clues that suggested that Shan Gudao faked his death and planned a series of events behind the scenes. He claimed to be a descendant of the Nanyin royal family. In order to prove that he was not inferior to Li Lianhua, he designed a fake death and triggered a war. However, no conclusive information was provided to reveal the true identity of the person in the coffin. Therefore, I don't know who Shan Gudao is in the coffin of Lotus Pavilion.
Shan Gudao was a character in the ancient costume suspense martial arts drama, Lotus House. Initially, he was Li Xiangyi's loyal senior brother, but later he became a sinister villain. In the movie, Shan Gudao found clues in the palace while searching for the Mother of Hellfire and decided to take action against the Emperor. After Li Lianhua learned of Shan Gudao's ambition, she decided to enter the Imperial City to stop him. In the plot, Shan Gudao had some other actions and plans, but the specific details could only be understood by watching the drama.
Shan Gudao was not a descendant of Nan Yin. The reason why he thought he was a descendant of Nanyin was because Li Xiangyi's brother, Li Xiangxian, gave him a jade pendant. After losing his memory, he was found by the people of Nanyin, so he mistakenly thought he was a descendant of Nanyin. The real descendant of Nanyin was Li Xiangyi. He was the great-grandson of Princess Xuan Fei, the princess of Nanyin.
In the original novel, Fang Duobai liked Li Lianhua. In the original novel of " Lotus House," Fang Duobing was Li Lianhua's friend, and they had a close relationship. Fang Duobing knew Li Lianhua very well and had always regarded her as a peer. He had never asked Li Lianhua to return to her identity as Li Xiangyi. Although many people had seen that he was Li Xiangyi during the investigation, Li Lianhua had always used all kinds of words to brush him off and never admitted her identity. Therefore, it could be said that Fang Duobing was a sincere friend to Li Lianhua. He liked and supported Li Lianhua.
Li Lianhua was a descendant of the Nanyin bloodline, but Shan Gudao was not.
Shan Gudao was three years older than Li Lianhua.
Dan Zhigang and Si Teng had finally reunited. In " Si Teng," Shan Zhigang recognized Si Teng excitedly when he first saw her in the hospital and chased her to the door to confirm. In addition, Dan Zhigang's words," So it's her," also indicated that he had a special relationship with Si Teng. Therefore, it could be confirmed that Shan Zhigang and Si Teng had recognized each other.
