The task of obtaining testimony and evidence against Cai was entrusted, perhaps purposely, to Fukangan who also conducted the trial. Cai's successful defense of Chulo was discredited and was attributed to the bravery of the civilians. The whole case was clearly a conspiracy. Cai was forced to sign a confession and on this ground he was slated for execution. In August he was delivered to Beijing for reexamination, but he refused to admit his “crimes,” asserting that his confession was obtained by force. When questioned by the Zianlong emperor himself, he denounced the injustice done him and even argued with the emperor. For this breach of etiquette he was beheaded on August 22, 1788.

Huang Sangui (黃三桂) fared much better. In a memorial submitted to the Qing court in Beijing, Colonel --u Tingshi (徐鼎士) lauded Huang for his surprise attack on --inzhuang (新莊), which was also known as Haishan-kou (海山口). The colonel memorialized that Sangui “conquered Haishan in one day.” Unaware of Haishan being the self-same city of --inzhuang, Qianlong awarded a “Yellow Ceremonial Jacket” of a mandarin to Sangui. The emperor read Haishan separately. He thought Sangui had conquered in one day “Sea” and “Mountain,” which, combined, meant a large land area facing the sea. Haishan is still used today to designate the vast area surrounding --inzhuang. When the Japanese started ruling Taiwan in 1895, they designated the whole area as Kaizan-gun (開山郡) or the Sea-Mountain district, which was placed under the jurisdiction of the prefecture of Taihoku (Taipei) that included the special municipality of Taipei, the three counties of Taipei, Taoyuan and Yilan, and the city of Keelung.

After the rebellion of Lin Shuangwen, Sangui had a huge garden erected at Banka, which he named Satisfactory Garden or Suiyuan (遂園), where he hoped to live in quiet retirement. After a few years in retirement, he contracted an incurable disease. Legend has it that when he was on his deathbed, with all his family wishing him recovery, the sky darkened during the broad daylight all of a sudden. A heavy downpour followed lightning and thunderclaps. Then the jet-black sky was torn open by a blazing fireball. It fell into Satisfactory Garden at the back of Sangui's huge mansion in Banka. Sangui expired when the fireball hit his beloved garden.

The bereaved family inspected the garden after Sangui's funeral, and found a small crater three feet in diameter and five feet deep. Workers were sent for to find what was at the bottom of the hole. They dug out a stone weighing 70 catties or 42 kilogram. Everybody believed it was a star that fell from the skies to mark Sangui's death. In fact, his followers were convinced he was that star.

The meteorite was taken back to the Huang mansion and Sangui's offspring began to worship it as a sort of his reincarnation. It is said to emit light at sunset for years. Still kept at the Huang house on Huaxi Street in the Wanhua district of Taipei, the stone does not emit any light anymore anytime.
