Ng Bak Choon was born in the Chao’an district of Guandong, China in 1869. As a young man, he made his way to Pontianak in West Kalimantan, where he worked at a sundry shop. Later he turned his sights to Kuching and founded his shop Siang Hak Huat (上合发) at No. 10 Main Bazaar. He chanced to gain the confidence of the 2nd Rajah, Charles Brooke, who entrusted him with the development of vast swaths of land at Chawan Road and Simpang Tiga.
Around 1910, Ng Bak Choon established the Siang Hak Huat Farm (上合发园) on Chawan Road. It practiced mixed farming on a large scale, raising cash crops like rubber, peanut and various fruits and vegetables as well as livestock such as fish, pig and chicken. On top of his thriving businesses, the Teochew entrepreneur was elected to the chair of Soon Hong Kongsi (顺丰公司), predecessor of the Teochew Association.
The Ng commercial empire included, in addition to the 560 acres of the Siang Hak Huat Farm, large tracts of land located at Tabuan Road (also called Sa Kak Bo), Central Road, even in Musi and Kanowit. In the 1920s, Ng Bak Choon was directed by the rajah to build 36 shophouses at Batu Kawa, replacing the old shops of Sekubang. He passed away aged 65 in 1933.
黄木春先生
潮州人黄木春1869年出生在广东潮安县，少年时南来，先抵达西加里曼丹的坤甸经营杂货店，然后转战古晋，在海唇街门牌10号创办上合发宝号。在机缘巧合之下，他得到砂拉越第二代拉者查尔斯布洛克的信任，拉者将诏安路和新邦迪卡地区的大片土地交给他去发展。
1910年前后，黄木春位于诏安路的上合发园正式开芭，这是一座大型的综合性农场，种植树胶、开池养鱼、养猪、养鸡、栽种蔬果，同时也大规模种植花生来提炼食油。此时，上合发宝号的业务迈向巅峰，黄木春还被推举出任顺丰公司（潮州公会前身）的总理，倍受各界尊敬。
黄木春的商业王国，还包括大片大片的地皮，除了上合发园的560多亩土地，市区三角坡、中央路、远一些的模西甚至加拿逸，都有黄家的地皮。值得一提的是，1920年代黄木春还在拉者的指示下，在石角建了36间店屋，取代原有史古邦的旧巴刹老店。1933年，黄木春逝世，享年65岁。
