Chong was born in Sarikei in the then-British protectorate state of Raj of Sarawak to a couple who were owners of a Chinese drugstore. The oldest of seven siblings, he completed his high school education at St. Anthony's National Secondary School in his hometown and later also attended St. Joseph's National Secondary School in Kuching.[1][2][3] After his father had fallen ill, Chong returned home to take over the helm at the family business after having only completed Form 3 (Year 10) of his high school. Nevertheless, he self-studied and eventually took teaching jobs at his alma mater, St. Anthony's, including teaching Form 4 and 5 (Years 11 and 12) morning classes between 1952 and 1962.[1][2]
On 27 September 1962, Chong, aged 27, used his savings from his teaching days to pay for his ship ticket to London, United Kingdom to begin his studies after being accepted into Lincoln's Inn.[1][2][3] Working tirelessly, he finished his studies in 18 months compared to the usual three years.[4] Upon completion of his studies and admission to the English Bar in February 1965, Chong would return home to practice and eventually founded the law firm "Chong Brothers Advocates" in 1968 alongside his younger brother, Chong Siew Chiang.[2][3]

He held this position between 1975 and 1979.[3] During this time, he was appointed Commissioner for Oaths (August 1978) and later Notary public (October 1978).[1]
