He has published more than 60 books, many of which have been adapted as films. He writes under the pseudonym of "Nine Knives".

Ko was born on 25 August 1978 in Changhua County, Taiwan. He was the second of three sons to parents who owned a pharmacy. Ko discovered his love of writing when he penned a story as part of his university application. He graduated from National Chiao Tung University with a Bachelor of Science (B.S.) in management science and earned a Master of Social Science (M.S.S.) from Tunghai University.

He started writing fiction in 1999, and posted most of his first works on the Internet. Ko struggled through the first five years of his writing career, before branching out into multiple genres, namely horror, science fiction, and romance. He writes 5000 words daily, and at his peak writing pace published one book per month for 14 consecutive months. This set of work helped Ko's popularity rise in Taiwan. Ko has compared himself favorably to Louis Cha, Gu Long, and Ni Kuang.

"Jiubadao" was originally a song written by Ko as a senior high school student. The song's title stuck as a nickname when a tutor spotted students passing notes signed by Jiubadao and asked who he was. Classmates revealed Jiubadao to be Ko and he used the nickname as a pseudonym after graduating college.

In October 2014, Ko admitted to cheating on his girlfriend of nine years, Hsiao-nei, with television reporter Chou Ting-yu. In early May 2015, Ko confirmed that his relationship with Hsiao-nei had ended. Ko and Chou began dating in March 2016; they married in late 2017. On 4 April 2020, Ko announced the birth of their first child. Ko and his wife had their second child on 14 July 2022.

In October 2014, it was reported that Beijing had ordered works by Ko removed from shelves in China. A few weeks previously, Ko had shaved his head to show solidarity for Occupy Central with Love and Peace, the organization that started the 2014 Hong Kong protests.
