Goh began his education at Chung Hua School in Tutong[7] before continuing his studies at Sultan Omar Ali Saifuddien College,[6] a prestigious institution at the time.

[9] In 1970, Goh King Chin left his government role to establish GHK Motors, a company specializing in importing reconditioned secondhand cars, mainly from Europe, the United States, and Japan.

In 1973, his company secured rights to sell Daihatsu vehicles in Brunei, and by 1979, GHK Motors had become the sole distributor for Mitsubishi cars and trucks, further cementing its leadership in the market.

To further expand, he invested in ventures such as the GHK Auto Assembly Plant, Brunei's first commercial vehicle prefabrication factory, which officially opened on 31 July 2000, marking a pivotal moment in the nation's automotive industry.

"[13] Pehin Goh stated during a 2005 Legislative Council Meeting that the Chinese community admires the Sultan's leadership and credits his rule for the peace and tranquility they enjoy.

He reaffirmed the community's support and respect for Brunei's Islamic principles and governance, and he asked that officials make it easier for Chinese people who were born there to become citizens.

Goh also promoted giving foreign investors permanent residence (PR) status, claiming that this would boost small and medium-sized business expansion and attract more financial investment to Brunei.

According to Adanan Yusof of the Ministry of Home Affairs, foreign spouses and their children can apply for citizenship, and he noted that between 1958 and 2005, 42,600 individuals were granted permanent resident status, while emphasising that each country has its own distinct immigration laws.

He underlined that in addition to helping the country prosper, Bruneian Chinese held the Sultan, the administration, and the Islamic policies in high regard and supported them.

[9] At the 9th Legislative Council Session in 2013, Goh had previously expressed concerns about the difficulties stateless people in Brunei experience, especially with regard to travel abroad and property ownership.

[9] Having lived in Kampong Jangsak for over 30 years, he has witnessed significant changes in traffic patterns, particularly during rush hours, due to the development of a nearby school and mosque.

[20] At his home in Kampong Sungai Besar, Pehin Goh is known for hosting open houses during Chinese New Year, bringing together family and friends in celebration.
