Sifu Gim Jie Wei is a Wing Chun Sifu who has over 6 years of teaching experience. He started his martial arts journey when he was at the age of 9 years old. The first martial art he practised was Wushu style in his primary school. He stopped studying Wushu style after about 1.5 years because he had to transfer to another school due to his father's career. Although it was just a short period of time, he began to head his martial arts direction towards practicality instead of performance-oriented, as he was asked by one of his Kungfu brothers how to block his incoming attack. To his shock, he has no idea how to block a simple hammer fist punch towards his head. From that instance onwards, he started to drift his martial arts path from performing arts to self-defence arts.

At the age of 15 years old, he started his Wing Chun journey by learning the art from his uncle, Sifu Dr Yoon. He trained hard until he finished his secondary school. Before he travelled to another state to pursue his Bachelor of Engineering (Hons) in Mechanical Engineering, he had a few private lessons to sharpen his Wing Chun skills. During his university life, he has done lots of research on Wing Chun art from books and the internet. Although he did not have as much time as before, he has not stopped studying and practising Wing Chun. In 2022, he also registered Yam Sik Wing Chun Saan Sau Association under the Society Act 1966 with the assistance of his students and took the position of Chairperson in the association.

Now, he is a working individual while part-time studying Master of Engineering Science, he still teaches Wing Chun passionately. His teaching focuses on the practicality and usability of Wing Chun. He believes that the application of the techniques is the most important aspect when learning the art.
