Early career Zeng was once a safety officer at a
Shell production platform at
Pulau Bukom. He officially became a member of the Singapore-based political party Workers' Party (WP) on 18 August 1991 because "the
PAP government obviously wants an opposition in Parliament", He netted a quarter of the 22,000 votes cast, losing out to the PAP's Wang Kai Yuen. Zeng decided to leave the party that year because, in his words, "in politics, all the crows are black". In a 1996 lawsuit he was involved in, Zeng stated that he contested the 1991 general election only to gain publicity for his acupuncture business.
Perennial candidacy in December 2015. After leaving the Workers' Party, Zeng became a
perennial candidate for election in Singapore. He ran for the Mountbatten Single Member Constituency during the
2006 Singaporean general election, but was unsuccessful. Believing himself to be ineligible for candidacy, Zeng decided not to take part in the
2011 Singaporean general election. During the
2013 Singaporean by-election, Zeng decided not to contest as he suspected a conspiracy against him, claiming that he first needed "the President's pardon". He also explained that he wanted to give in to candidates of higher caliber than him, adding that "
fools rush in where angels fear to tread". In August 2015, he declared that he would be
contesting the
Potong Pasir Single Member Constituency, pledging to "fight until the end", but after less than a week he changed his mind, citing his being the only independent running, his good ties with
Chiam See Tong, and not wanting his participation to cause a
three-cornered-contest as reasons for his withdrawal. Furthermore, he revealed he could not have secured the
election deposit alone and was relying on his "fifteen compassionate backers".
Other ventures Having studied the subject in Hong Kong and Taiwan, and organised acupuncture meet-ups as the president of the World Acupuncture Voluntary Organisation (WAVO). After Zeng published controversial and self-admittedly "misleading" advertisements of it in 1991, the 28th World Congress of Acupuncture and Complementary Medicine, which was supposed to have taken place in Singapore, changed its host country to the
Republic of China. Zeng, in defence, cited "miscommunication" with the Medicina Alternativa Institute in Sri Lanka. As a philanthropist, Zeng funded the construction of a
mosque in an unspecified Bangladeshi village. It moved to
Toa Payoh and its sole basis of operations became selling healthcare products, including slimming oil and a "hair regrowth shampoo" made of vegetable and chocolate. He also owned a
MacPherson-based store. Zeng's Medical Centre folded after he was diagnosed with cancer. The work, which contains numerous references to the 1976 monster thriller
King Kong, was banned by the government upon its release. Benson Ang stressed the controversy surrounding Zeng, describing him as "Toa Payoh's nutty professor". Others facetiously dub him as an "election veteran" in Singapore while noting his tendency of not filing his nomination papers and his public antics; Ilsa Chan, writing for Toggle SG, billed Zeng as "the candidate who never gives up" but found his backing out of the 2015 general election bizarre. Singaporean comedian and blogger Lee Kin Mun, better known as
mrbrown, portrayed Zeng in a satirical video on the 2013 Punggol East by-election. Zeng is notable for his unorthodox, or a golden scarf. He was also seen in a
baju kurung and
songkok during the 2011 Singaporean general election. ==Personal life==
