Dato Lim quickly gained the trust of Ong and was soon promoted to manager of Teck Guan Company. Following Ong's death in 1940, Lim took on the role of trustee, responsible for both managing the business and caring for Ong's younger children. Under his guidance, Ong's second son,
Ong Kim Kee, was sent to Singapore to pursue his secondary education, while Lim also supported Ong's second daughter in her studies in China. During the
Japanese occupation, Lim faced imprisonment for a week due to jealousy from a Japanese businessman, who framed him for various wrongdoings; he was eventually released after a friend helped clear his name. Throughout the Japanese occupation, Lim frustrated the occupiers by refusing to provide information about the company, which led to him being beaten and imprisoned for three days before securing his release with the help of a friend. After the war, as the Chinese population in Brunei continued to grow, the need for an organization to support their welfare and address business disputes became apparent. This led to the establishment of The Chinese Association, which was officially registered in 1946 as a precursor to the CCC. Following extensive discussions, the committee agreed to the name change, and the CCC in Brunei Town was officially founded in 1947, with Lim appointed as its first president. In addition to his contributions to the business sector, Lim also made significant contributions to education. In 1941, he took over as chairman of the
Chung Hwa Middle School's board of directors from Ong, who had died the previous year. Lim held this position until 1943, during the most challenging years of the war. In 1961, when CHMS, BSB sought to construct a new two-storey classroom block, Lim eagerly led the fundraising efforts by becoming president of the building construction committee. Under his leadership, the new block was successfully completed within a year. Lim remained actively involved with the board until his death in 1993, making him its longest-serving member, with a remarkable total of fifty-two years dedicated to the school's development and success. == Political career ==
