(Yicai Global) June 14 -- Hansoh Pharmaceutical Group, Hong Kong's second-biggest initial public offering so far this year, surged on its debut today.

China's largest maker of psychotropics [HKG:3692] closed almost 37 percent higher at HKD19.50 (USD2.50), having soared by half earlier in the day.

The Jiangsu province-based company became only the second Hong Kong-listed drugmaker worth more than HKD100 billion (USD12.8 billion). Its HKD120.8 billion market value surpassed Wuxi AppTec's [HKG:2359] HKD108.72 billion.

Hansoh Pharmaceutical's successful debut also reportedly spawned China's richest couple as Zhong Huijuan, the company's founder, joined her husband as a multibillionaire.
