Shap Ng-tsai (Chinese: 十五仔) was a Chinese pirate active in the South China Sea from about 1845 to 1859. He was one of the two most notorious South China Sea pirates of the era, along with Chui A-poo. He commanded about 70 junks stationed at Tien-pai (Tienpak), now Diancheng in Dianbai County, about 180 miles west of Hong Kong. Coastal villages and traders paid Shap Ng-tsai protection money so they would not be attacked. Chinese naval ships that pursued the pirate were captured and their officers taken captive and held for ransom. The Chinese government offered him a pardon and the rank of officer in the military but he did not accept.
End of pirate career
Shap Ng-tsai was blamed for sinking an American ship and three British ships carrying opium in the spring of 1849. That September, a squadron of British ships went to Tien-pai and found 100 captured ships there held for ransom, but failed to find the main pirate fleet. Then in October, three British ships and eight Qing navy junks pursued the pirates to the islands and channels of Haiphong, Vietnam and fought the pirates for three days. Afterwards the expedition reported the destruction of fifty-eight pirate junks carrying 1,200 cannons and 3,000 crewmen. Shap Ng-tsai escaped the battle with six smaller junks and 400 men. He later surrendered to the Chinese government and accepted the military position.
