Wei Zisu

Biodata

Background / History

Childhood and His Brother’s Disappearance

Wei Zisu’s parents, Wang Fen and Wei Guoyong, initially worked in factories before opening a small electronics factory. Their work left them little time for their two sons. Shortly before Wei Zisu’s seventh birthday, his father promised an amusement-park outing; his younger brother disappeared during that trip 62.

Wei Zisu spent the next twenty years blaming himself. His father destroyed his brother’s belongings and photographs, supposedly because his mother could not endure the reminders. Without a photograph, Wei Zisu relied on memories of their similar appearance, especially their eyes 60 62.

Finding his brother became a major reason for entering entertainment. It also influenced his decision to accept Sun Liang’s engagement, since Sun Liang had the resources to help search 61.

Early Career and Engagement to Sun Liang

A commercial attracted attention to Wei Zisu during his first year in entertainment. After a renowned director cast him as a film lead, Sun Liang began pursuing him, visiting the set, giving gifts, and placing orders with his parents’ struggling factory. His mother encouraged the relationship 3.

Despite that promising start, Wei Zisu remained obscure five years after his debut. He had appeared in minor commercials and four productions, none of which had aired. Industry colleagues mocked him as someone who was “still a newcomer” after five years 1.

His engagement deteriorated through Sun Liang’s indifference, infidelity with Yuan Zizhen, and unfulfilled promises concerning his brother. Wei Zisu rejected an offer to bear a child with Sun-family inheritance rights and dissolved the engagement at the Civil Affairs Bureau. When Sun Liang insulted his missing brother, Wei Zisu punched him and followed with a thorough beating 3 4.

Although he initially attributed his career problems to bad luck, Sun Zhe was later shown ordering an associate to obstruct the release of Wei Zisu’s productions. Sun Zhe eventually allowed Eastern Wind Art through review as part of an attempt to make himself indispensable 78.

Marriage to Yin Zhengchuan

After turning twenty-seven, Wei Zisu entered the Civil Affairs Bureau’s alpha-matching process. He could not afford the alternative fine, but refused to accept an unsuitable spouse. His mother had also refused to lend him money and pressured him into leaving his savings with her, hoping to force a reconciliation with Sun Liang 5 6 8 31.

He met Yin Zhengchuan among his first batch of matches. Yin’s nervous, formal introduction amused him, and the two registered their marriage approximately an hour after meeting 9 11.

Wei Zisu announced the marriage to his filming crew and later confirmed it on Weibo despite his agency’s objections. He subsequently visited Yin Zhengchuan’s family in Shandong, discovering that their circumstances were far wealthier than his understanding that they simply grew vegetables 20 30 34 35.

Their wedding included a Chinese ceremony at home and a Western ceremony at Swan Lake. Because Wei Zisu attended without his own family, Yin Zhengchuan removed the bridal pickup, attendants, and customs he considered unfriendly to the bride 46 47.

Wei Zisu initially described his affection for Yin Zhengchuan alongside his affection for the rest of the Yin family. Their relationship gradually became explicitly romantic: he reassured Yin that Baozhu was family rather than a romantic rival, and later directly told him, “I love you” 40 97 134.

Finding Gu Ziran

During a Still in Love livestream, Wei Zisu publicly appealed for information about his brother. Zhu Zhu later found an old restaurant staff photograph containing Gu Ziran, whose eyes closely resembled his. Wei Zisu and Yin Zhengchuan followed the lead to a welfare institute, where they learned that Gu Ziran had an intellectual disability 60 90 91.

When Wei Zisu finally found Gu Ziran with Sun Zhe, he learned that Sun Zhe had arranged plastic surgery to make the boy resemble him. Sun Zhe argued that welfare-institute records ruled out any family connection because Wei Zisu’s parents had previously visited and denied their missing child was there. Wei Zisu refused to accept that explanation without a DNA test 132.

The test confirmed that Gu Ziran was his younger brother, Wei Ziran. Confronting his parents, Wei Zisu uncovered that they had deliberately abandoned the child because of his disability, then allowed their older son to carry the blame. He severed ties with them and refused to let them meet Gu Ziran 134 135.

Wei Zisu brought his brother into his home and promised lifelong protection. Yin Zhengchuan helped Gu Ziran settle in while Wei Zisu resumed work promoting Eastern Wind Art 136.

Conflict with Sun Zhe and His Parents

For Grandma Wang’s sake, Wei Zisu initially agreed not to pursue Sun Zhe further if he stayed away from Gu Ziran. He withdrew that leniency after Sun Zhe attempted to abduct Gu Ziran and injured Yin Baozhu 139 145.

His parents later appeared on a live family-reunion program, accusing him of hiding his brother. In private, they revealed plans to arrange Gu Ziran’s marriage. During the resulting controversy, Wei Zisu’s agency publicly cut ties with him—an outcome he welcomed, having already decided against renewing his contract 168 169 170.

After Grandma Wang’s funeral, Wei Zisu spotted Sun Zhe, followed him by car, and notified the police. Their confrontation became a fight, followed by an attempted kidnapping when Sun Zhe’s hired men intervened. Wei Zisu seized a thug’s dagger and wounded him to escape; approaching police sirens forced the group to flee 184 185.

Although experienced in staged combat, Wei Zisu was shaken by his first real knife attack. He repeatedly washed his hands afterward and worried that Sun Zhe’s threats might extend to Gu Ziran or the Yin family 185 186.

Wuhan and Later Career

During the Wuhan crisis, Wei Zisu persuaded Yin Changjun to let him accompany a relief convoy. He drove for fourteen hours without telling Yin Zhengchuan beforehand and reunited with him at a checkpoint. After quarantine, the couple remained in Wuhan for more than two months before returning together to Shandong 198.

He continued acting and appearing on variety shows. Later projects included Couple United in Heart and a film in which Yin Zhengchuan played his character’s lover, Xu Yunchuan. By the later bonus stories, a livestream on his main account attracted several million fans within minutes 213 247 251.

Appearance

• Fair skin and a slender-looking build: Yin Zhengchuan specifically names his fair skin as a strength; Sun Liang is surprised by the force behind his seemingly frail appearance 4 55.
• Striking looks: His early commercial drew considerable attention, while his period-drama styling makes him resemble a young nobleman brought out of a book 3 12 18.
• Eyes resembling his brother’s: Their similar eyes become a crucial clue in identifying Gu Ziran 60 90 91.
• Notable screen styling: Appears in high ponytails and elaborate historical costumes, as well as a mermaid costume with a pearl-decorated, flesh-colored top and large tail 12 15 102.

Personality

Wei Zisu often appears calm and emotionally reserved, but responds to mistreatment with blunt sarcasm rather than appeasement. He refuses to reconcile with Sun Liang for financial security, rejects demeaning marriage candidates, and publicly confirms his marriage despite his agency’s preferred publicity strategy 3 8 9 30.

He is conscientious about acting. For a novel adaptation, he repeatedly reads the source material, writes a character analysis, and studies readers’ interpretations. He treats criticism of his casting as something to answer through his performance rather than argument 12.

His composure conceals deep guilt about his brother. He also has a tendency to blame himself: his mother’s criticism once convinced him that his incompatibility with Sun Liang was a personal defect. Cui Xiangxiang challenges that belief, while Yin Zhengchuan helps him recognize that he need not hide his emotions or accept his father’s abuse 20 61 93.

With people he trusts, Wei Zisu is affectionate, protective, and playful. He comforts Yin Zhengchuan’s jealous insecurities, exchanges teasing remarks with him, and promises Gu Ziran a permanent home. His concern for others can outweigh his strong preference for cleanliness, as when he nurses Yin Zhengchuan through mushroom poisoning 79 86 136 159.
