Jiang Cheng is the current leader of the Jiang Clan. Titled Sandu Shengshou, he is the brother of Jiang Yanli, the martial brother of Wei Wuxian, and the uncle of Jin Ling. He is a straight-laced and strict man who abides by the rules. He has a deep care for his family and friends and knows to respect his elders.
At the beginning, he had a good relationship with Wei Wuxian, despite the latter often annoying him with his mischief. After the death of his parents, he had to quickly step into the role of the new clan leader without Wei Wuxian by his side as the latter was trapped in the Burial Mounds at that time. He led his clan, which was still recovering from the invasion of Lotus Pier, along with other clans and played a major leadership role in the Sunshot Campaign. However, his hatred for the Wen Clan caused a great strain in his relationship with Wei Wuxian, who regarded Wen Ning as a close friend and kept the survivors under his care. This eventually became pure hatred when Wen Ning accidentally killed his brother-in-law and his sister died while protecting Wei Wuxian. However, ultimately, he gives up this hatred after learning how Wei Wuxian had sacrificed his Golden Core for him. Though despite all these, he still loves his nephew Jin Ling, and acts in a strict manner like his mother had done to him as a child. He would sacrifice his life in order to protect his nephew.
