TAIPEI- Chiang You-ching, great-grandson of late Kuomintang leader Chiang Kai-shek, stood the trial on Thursday in Taipei, on charges of threatening the Taiwan American School (TAS), his alma mater, via Facebook and emails.

Chiang, 23, pled not guilty at Thursday's first hearing, claiming that he was merely venting emotion on his Facebook account.

He was charged with threatening the TAS since August, and especially its administrators via Facebook and e-mail.
