The surrender of the Tung-Ning Kingdom was not as straightforward as commonly known, i.e., a simple capitulation announcement from Koxinga's grandson and heir 鄭克塽Cheng Ke-Shuang. As in Koxinga's negotiation with Coyett, Cheng Ke-Shuang must also deal with 施琅Shi Lang, the Ming-Cheng turncoat.
In Shi's report to the Qing Court, he stated,
"…查鄭克塽年尚幼樨，未諳大體，操縱指揮，權皆出于劉國軒、馮錫範二人。茲特令朱紹熙回台灣傳諭，果真心投誠，必須劉國軒、馮錫範來臣軍前面降，將人民土地悉入版圖。其偽官兵遵制削髮，移入內地，聽遵朝廷安輯。…（dated Aug 3, 1683, or 康熙Kang-xi 22nd year, double 6th month, 11th day)
In other words, Shi blamed everything on Liu Guo-shian and Feng Shi-feng, the true power behind Cheng. Both of them must therefore openly surrender. The Ming-Cheng people and land would be ruled under Qing. All officers and soldiers would shave their head in the Qing style and moved inland.
On Sept 17, 1683, Cheng issued the first report/announcement, namely,
He professed young and ignorant having been raised by his grandfather and father, and conceded the heaven-mandated benevolent rule of the Qing emperor. And that he was really just a minion who would now pledged his most sincere loyalty to Qing.
Shi, however, was a practical man, on Sept 19, 1683, he again reported to the Qing Court, that
The seals (chops) of the Ming-Cheng officials including the Yan-Ping kingship had been received.
After this, on Oct 5, 1683, Cheng Ke-Shuang surrendered a second time:
His request of relocating back home to Hokkien was denied and together with his family, were held hostage in Beijing. His loyal followers, most were seamen, were banished to various penal colonies in mainland China to die.
