The history of the Yam Kai Wai Wing Chun Academy, or also known as Yam Sik Wing Chun or Gim Jie Wei Wing Chun Academy, formerly known as Yam Sik Wing Chun Saan Sau Association and UTAR Wing Chun, began when Sifu Gim founded the Wing Chun class at Universiti Tunku Abdul Rahman (UTAR) Sungai Long Campus, Malaysia in 2017. Sifu Gim's application to establish a UTAR Wing Chun Club on campus was rejected and was compelled to place Wing Chun under the Wushu Club as a division, despite having over sixty registered members at the time. As Sifu Gim's Wing Chun class primarily targets university students, he focuses his teaching on Wing Chun's Saan Sau techniques. Saan Sau consists of simple and practical combinations formed by various Wing Chun hand and foot techniques. The reason is that Saan Sau allows beginners to quickly get started and immediately apply their skills in combat, which is particularly appealing to young people. Therefore, Sifu Gim incorporates "Wing Chun Saan Sau" into his Wing Chun class and includes the term "Wing Chun Saan Sau" on early posters, clothing, etc. Today, his Wing Chun class no longer solely emphasizes Saan Sau.

任界維詠春武館，或任式詠春，前身為任式詠春散手公會、拉曼大學詠春或優大詠春的歷史是從任師傅2017年在馬來西亞拉曼大學雙溪龍分校創辦詠春班所開始。任師傅申請在校園內成立詠春學會時遭到拒絕，並被迫將詠春歸入武術學會作為其旗下的一個分部，儘管當時已有超過六十人報名加入。 由於任師傅的詠春班的目標受眾是大學生，他將教學重心放在詠春的散手。散手是一套套由各個詠春手法和腳法組成既簡單又實用的組合。其原因是因為散手可讓初學者快速上手，並能立即應用在對打之中。這點更受年輕人的歡迎。因此，任師傅將「詠春散手」應用於其詠春班中，並在早期的海報、衣服等印上「詠春散手」四字。如今，他的詠春班不再只是着重於散手。
 
In early 2020, the COVID-19 pandemic erupted globally. Malaysia implemented a Movement Control Order (MCO), prohibiting various activities, including Sifu Gim's Wing Chun class. Faced with no other option, he had to cancel the fee-based physical Wing Chun class and transition to a free online Wing Chun class. Unsurprisingly, the number of participants plummeted drastically, from over twenty to just two or three. Nevertheless, Sifu Gim persisted in teaching Wing Chun. It wasn't until 2022 when MCO were lifted that the physical Wing Chun class could resume. However, there was no improvement in participation numbers. Several affected extracurricular activities stopped inviting professional instructors and switched to operating models similar to hobbyist clubs, offering free-of-charge services without dedicated guidance. This indirectly led university students to prioritize joining other non-fee-based clubs and societies over joining the Wing Chun class with a qualified instructor. It was around this time that Sifu Gim realized confining the Wing Chun class to university campuses was not a sustainable solution. With the help of his disciples, he followed his Sifu's example and registered the Yam Sik Wing Chun Saan Sau Association Kuala Lumpur and Selangor in 2022 under the Societies Act 1966. The association is also known as "Yam Sik Wing Chun" in short. He hopes that after the establishment of this association, his former students who have graduated and the public outside of the campus can have access to Wing Chun. 

 

2020年初，新冠肺炎疫情於全球爆發。全馬來西亞實施行動管制令，各種活動被禁止，當中包括任師傳的詠春班。逼於無奈，他唯有將收費實體詠春班取消，並轉換成免費線上詠春班。毫無疑問，參與人數直線下降，由原本的二十幾人跌至兩三人。 儘管如此，任師傳仍然堅持傳授詠春。一直到2022年行動不再受管制，實體詠春班才得以恢復。可是，參與人數並沒有好轉的迹像。有好幾個受影響的課外活動都紛紛放棄邀請專業導師，改為不收費、類似愛好者俱樂部的營運模式，不再有專人指導。這變相導致大學生優先選擇加入其他不作收費的學會而不加入有專人指導的詠春班。 也在這個時候，他察覺到將詠春班侷限於大學內不是一個長久之計，於是，他在徒弟們的幫助下效仿了其師父的做法，於2020年根據《1966年社團法》註冊了雪隆任式詠春散手公會。「任式詠春」也是該公會之簡稱。他希望成立了此公會之後，他已畢業的徒弟們和校園外的大眾可以接觸詠春。
 
On 9 August 2024, Sifu Gim officially ceased the operation of UTAR Wing Chun to devote more of his efforts to the Yam Sik Wing Chun Saan Sau Association. Later, on 1 December 2025, he has also ceased the operation of the Yam Sik Wing Chun Saan Sau Association to fully focus on his academy, Yam Kai Wai Wing Chun Academy. Long duration monthly training is now held regularly to accommodate the tight schedule of his students. He is a strong believer of " Traditional style of Kungfu, modern way of training it."

2024年8月9日，任師傅正式結束優大詠春的運作，將更多心力投入任式詠春散手公會。後來，於2025年12月1日，他也結束了任式詠春散手公會的運作，以便完全將重心擺放在他的任界維詠春武館。如今，為了配合學生緊湊的時間表，已定期舉辦長時段的每月訓練。他堅決相信「傳統式功夫，現代化訓練。」
