Who is Cheng Xiaojiao in the TV series "Huo Dongge"? Tell us about his origins.

In the early years of the Republic of China, the Japanese invaders were aggressive and tyrannical. Huo Dongge was raised by Chen Zhen of the Jingwu Sect since he was a child. Huo Dongge is the son of the late hero Huo Yuanjia. After Chen Zhen's death, the Jingwu Sect gradually declined, and Huo Dongge later worked as a porter at the dock to make ends meet. In order to save the country and fight against Japan, patriots Chen Gongzhe, Lu Yuting, Yao Zhanbai and others found Huo Dongge to instill patriotism in him based on his father's deeds of petitioning for the people, and taught him martial arts to revive Jingwu Sect. Afterwards, Huo Dongge and Chen Songzhe and a group of patriots resisted Japanese rule and specifically opposed the Japanese. In order to save people of all walks of life from the suffering of Japanese imperialist rule, they were not afraid of hardships and sacrifices, and carried forward the chivalrous spirit of the Jingwu Sect...

Huo Dongge is a well-known legendary hero. In the play, Huo Dongge, played by Qian Xiaohao, is the son of Chinese national hero Huo Yuanjia. Because he failed to learn martial arts, he did not dare to disclose his life experience to others for fear of damaging his late father's reputation. At that time, the passionate young man Chen Gongzhe (Liu Zhirong) visited Dongge and wanted to use his identity to carry forward Huo Yuanjia's "martial and patriotic" spirit. Dongge declined for fear of betraying his trust; later he got Cheng Xiaojiao (Xu Xiaoming), Liu Zhensheng (Tan Rongjie) and others. After repeated persuasion from my seniors, I finally made up my mind to shoulder the responsibility of carrying forward the Jingwu spirit of "Only the essence is the only one, which is literature but martial arts"!
