Union Metal Works (aka Unimet) was one of the leading manufacturers of pressure lanterns in HK alongside World-Light, Glory, Lea Hin and Chung Mei profiled earlier in the group. As shown in the 1962 ad above, Union also manufactured kerosene pressure stoves, paraffin space heaters and kerosene water heaters under the SOLAR brand. The firm traced its origin to Union Cycle Manufacturing, the bicycle manufacturer in HK started before the War which was converted to making pressure lanterns after the War. The firm was first controlled by the family of General Chen Chi-tang (陳濟棠,1890-1954), the warlord known as “the Celestial King of the South” as he ruled over Guangdong province from 1928 to 1936 and remained in his family’s control until 1964 when his son Chan Shu-woon (陳樹桓,1921-2003), a prominent civic leader at the time, left Hong Kong. The Chan family was succeeded by Sheung-hong Sung (宋常康,S.H. Sung, 1917-2018), the scion of a prominent Chinese Christian family who recently died on January 23rd 2018 at the age of 100. Outside of Unimet, the Chan and the Sung families have founded many companies, schools and organizations in HK and abroad.

Union Metal Works started its life as The Union Cycle Manufacturing Co Ltd (合衆製車), which according to Made in Hong Kong (Turner, 1988) was the first manufacturer of bicycles in Hong Kong founded in 1936. As a firm, it was first incorporated in 1939 and registered its trademark in 1941. The firm had its plant at 522 Castle Peak Road in Kowloon and promoted its products by sponsoring inter-school cycling contests like the 1941 one mentioned above which involved schools such as La Salle College and Pui Ying Middle School and Union provided 50 bikes.

It is unclear as to when exactly the family of General Chen got involved with Union but the year of its founding (1936) coincides with the year General Chen fled to Hong Kong when he lost control of Guangdong after the defection of his lieutenants (particularly in the air force) to Chiang Kai-shek’s government in Nanking. Born into a Hakka family in Guangxi, General Chen joined the revolutionary cause as a teenager and ruled over Guangdong province from 1929 to 1936 during which he was credited for modernizing the province and his rule was generally regarded as the “golden era” in the pre-War period.

General Chen came to HK with a sizable fortune and according to reports, he had purchased 98 properties in Hong Kong including seven houses with garages on Boundary Street in Kowloon, earning the street the nickname of “Sau Ying Street” (秀英街, Sau-ying a reference to Chan’s wife Mok Sau-ying 莫秀英).His older brother Chan Wai-chow (陳維周), a former fortune teller whom he placed in charge of the lucrative salt administration in Guangdong, also came to HK with his family and bought lots of properties in the North Point area including Kai Yuen Terrace. When the Japanese occupied HK, Chen managed to escape to Chungking where he was given government positions and after the War, he was appointed Governor of Hainan Island before fleeing to Taiwan where he died in 1954.

After the War, Union Metal Works was incorporated in 1947 with HK$1 million in registered capital to manufacture ”Solar” brand of pressure lanterns and “Wheel and Torch” brand of kerosene stoves. Chen Kwang-seng (1916-2005), the UK trained engineer and son of General Chen Ming-shu (who like Chen Chi-tang rebelled against Chiang and was exiled to HK) was Unimet’s first chief engineer. In 1951, Chen left his job at Unimet to work with the Tang brothers to relocate their HK Nail Factory to Tientsin (see article). He was purged during the Cultural Revolution and returned to HK in 1978.

According to the article below, the plant which occupied 20000 square feet had production capacity of 15000 lamps (200W, 300W and 500W) and 5000 stoves (single and double burners) monthly and its lamp production represented 80% of HK’s total output.

Chen Chi-tang had a total of 18 children, of which 7 sons 4 daughters are children of his beloved wife Mok Sau-ying. Unimet chairman Chan Shu-woon was the third son but the eldest son by Mok and as a result was his father’s favorite.  Born in Canton (which is why his other Chinese name is 陳穗生), Shu-woon attended Tak Ming Middle School (德明中學, named after Sun Yat-sen whose original name was Tak-ming) in Mongkok which was founded by his father in 1934 and graduated from Lafayette College in Pennsylvania in 1944. After the War, he returned to Hong Kong where he became the head of a string of businesses including Unimet,Great South Fishing (廣南漁業, the largest fishing firm in HK at the time, to be covered), Yu Man Bank (裕民銀業, opened in 1947), Far East Fishing (遠東漁業公司) in Macau and a soda bottler in Borneo. He became the headmaster of Tak Ming in 1954 after the suicide of his fifth brother Chan Shu-kan (陳樹庚), and under his leadership, Tak Ming had growninto a large scale educational organization by 1960 offering kindergarten to tertiary education (under Tak Ming College 德明書院) with over 12000 students enrolled.In addition to Tak Ming, Chan Shu-woon was chairman of Shou Shan College in North Point, council member of Chu Hai College and Kwong Tai College and life president of Eastern Athletic Association. From business and education, he entered the realm of politics and in 1956, he won the Urban Council election with the third highest vote as a Reform Club candidate and in 1963 won re-election with the highest vote as an independent. At the peak of his success however, he was sued by his political rival Brook Bernacchi for alleged corruption during his election campaign and bowing to other political pressure (according to his classmate the school uniform maker and author Fong Foon-lit, it was the Special Branch of the HK Police which was concerned about his ties to the KMT regime in Taipei), he abruptly resigned from all his positions in HK in mid-1964 and left for the San Francisco Bay Area where he pursued graduate studies at Stanford.

Back in HK, the fishing businesses were shut down, Unimet was sold to S.H.

Cheng (鄭潤才, first husband of Bo Hing) took over as head of Tak Ming but one by one the schools began to shut down between 1977 and 1986.There are over 100,000 alumni of the HK Tak Ming schools worldwide including Taiwan tech billionaire Barry Lam, former legislators in HK and Taiwan and many overseas Chinese leaders.Many of Shu-woon’s siblings were also involved in education. His older brother Chan Shu-kwan (陳樹坤) was the head of Tak Ming’s Wanchai branch before starting his own English school. His tenth brother Chan Shu-Park (陳樹柏, 1929-2013) was an electrical engineering professor at Santa Clara University for three decades before founding the International Technological University in San Jose in 1994and co-authored two engineering textbooks with his brothers Chan Shu-Gar (陳樹家, 1927-2013)and Chan Shu-yun (陳樹潤, d.2009) who were both academics. His sister Bo-hing Chan (陳寶馨, 1929-2008) founded what became the Takming University of Science and Technology in Taipei in 1965 and together with her second husband Hawaiian dentist Dr. Lawrence Tseu (鄒錦榮) made significant gifts to Harris Manchester College at Oxford which named its largest building after them.The youngest brother Chan Shu-kit (陳樹杰, 1935-)graduated from Virginia Military Institute, started Pak Nam College (伯南英文書院, named after his father whose alias is Pak Nam) in North Point in 1961 before changing career in 1973 when he started the Lei Garden restaurant (利苑酒家), which now has 24 branches in HK, Macau, China and Singapore.
