Ni Kuang wrote 150 Wisely stories in the form of 145 novels, most of which have a serial number to reflect the chronological order of their year of publication.
According to Ni Kuang, when he decided to publish the Wisely Series as a collection in the 1970s, he discovered that Ming Pao did not retain all the copies of his previous works.
Luckily for him, he encountered a reader, Wen Naijian (溫乃堅), who collected all the copies of his stories published in Ming Pao.
According to Ni Kuang, the character's name was inspired by Wesley Village (衛斯理村) along Tai Hang Road near Jardine's Lookout in Hong Kong.
The village was named after John Wesley (1703–91), an English cleric who founded the Methodist movement within Anglican Christianity.
He lets his general manager run the company and spends his time travelling around the world and solving mysteries.
