After Tjung returned to the Indies, he had worked at a telephone company and became a lawyer before being appointed as a deputy prosecutor in
Pangkal Pinang's court. He also founded, and later led, the Bangka branch of the Chinese Association. In 1950, following the Senate's dissolution and the defederation of the
United States of Indonesia, Tjung was appointed to the
Provisional People's Representative Council as a "minority representative", alongside several other Chinese Indonesian politicians. He joined the
Catholic Party in 1953, and he served in the
People's Representative Council as a member of that party until 1960. Within that party, he was a member of its central board between 1953 and 1959, and its deputy general chairman between 1956 and 1958. During and after his time in the council, Tjung served as a director of several mining companies, including at
Aneka Tambang where he was its financial director between 1968 and 1974. He died in February 1994. ==Views==
