Khaw Soo Cheang (1797–1882), other names Khaw Teng Hai and Kor Su Jiang, was born in Xiayu Township, Longxi County of Zhangzhou, China (present-day Longhai City). At the age of 25, he left China to Nanyang in search of a better life. He arrived in Penang, then later migrated to Thailand in 1822. Soo Cheang established a tin mining and shipping empire.
