Wang Jiting 王吉亭 came from a wealthy family in Shanghai, where his father owned a store dealing in foreign goods which was very popular with Shanghai's sizable and affluent foreign expatriate community. The son was educated in one of the city's better English schools, and grew up a very prominent figure in local society, well known among both Chinese and foreigners, and never lacking for friends. What was once called a "wealthy young man about town," he drove a car, rode horseback, loved to gamble and frequent Shanghai's better-class brothels.
By the early 1920s, Wang Jiting had acquired a strong interest in movies. He approached the Mingxing company's Zheng Zhegu, who he knew socially, and expressed the desire to get into this new, emerging industry. Zheng got him a part in the studio's next production,《Lured Into Marriage》, cast in the role of a worker. Zheng and director Zhang Shichuan were both impressed with Wang Jiting's silent acting facial expressions, and agreed that with training, the newcomer could become a good actor. They cast him again, this time in《The Good Brothers》(1925), and his performance led Zhang Shichuan to offer him a contract which included a training spot in the studio's acting school as well as film appearances.
The studio made considerable use of him in 1925, casting him first in《The Last Conscience》as playboy Tian Dexiu, who runs off with the miserly main character's mistress and a large amount of his money. This was the first film in which he was cast opposite Xuan Jinglin, the next being《A Shanghai Woman》, in which she was a high-class courtesan who marries a wealthy playboy (Wang) who later abandons her. Although newcomers, both quickly showed talent for playing denizens of Shanghai's nightlife, perhaps stemming from their personal backgrounds. As someone who had spent much of his youth as a high-living womanizer, Wang Jiting's portrayals of playboys and libertines were right on target, while Xuan Jinglin was herself a former brothel inmate.
In《A Pitiful Girl》(1925), opposite Zhang Zhiyun and with Xuan Jinglin in a major supporting role, Wang Jiting played a pimp who specializes in trapping innocent girls into prostitution. His portrayal of the rogue was praised for how convincing it was, again perhaps due to his firsthand understanding of the brothel milieu and those who frequented it. In any case, critics called his portrayal both vivid and realistic, and it is considered his representative work.

After again playing the chief villain in《The New Person's Family》(1926) opposite Zhang Zhiyun, and with top stars Wang Yuanlong and Yang Naimei (themselves no strangers to Shanghai's nightlife) sharing top billing, Wang Jiting's reputation as an A-list movie bad guy had grown to where he was considered on a par with the Mingxing studio's top villain, Wang Xianzhai, so much so that other studios pursued his services, if not as a contract player, then as guest artist. Mingxing usually turned down such guest requests, but when Mingxing director and co-founder Ren Jinping 任矜苹 founded his own studio, Zhang Shichuan agreed to loan out Wang Jiting to make《Three Shanghai Women》for Ren, Zhang's close personal friend despite his now being a business competitor. But with this one exception, Wang Jiting (like fellow villain Wang Xianzhai) was steadfast in his loyalty to the studio which had given him his start in movies, portraying nasties for Mingxing from 1924 right up until the Japanese occupation of Shanghai in 1937 forced the studio to shut down.
Wang Jiting was also an important part of Mingxing's blockbuster martial arts success, the 1928-30 series《Burning of Red Lotus Temple》, in which he played one of the principal evildoers while also serving as assistant director.
But with the coming of sound, Wang's popularity began to decline. He spoke Mandarin, but not well, so while his film credits for the 1930s included some of the highlights of what is considered China's "Golden Age" of filmmaking, he increasingly found himself limited to smaller roles with fewer spoken lines. Another detriment to his career was that his old, dissolute habits of late hours, carousing and opium smoking were beginning to catch up with him physically, and steadily declining health led to his leaving movies in 1939. He returned briefly after World War II, but after making a few uncredited appearances in insignificant pictures, he disappeared from the scene for good. Wang Jiting died in Shanghai in the late 1940s, exact date unrecorded.
