In the authorised continuation short story The Jade Empress, Mr Pang is a passenger on board the cruise ship Jade Empress en route from Singapore to Hong Kong. An elderly Chinese gentleman, he had left Hong Kong many years ago and moved to Liverpool to make a new life. His wife and his son Tao stayed behind. When he finally earned enough money to bring them to join him, his wife had died and his son, now grown up, preferred to remain in Hong Kong. While in Liverpool he had a second wife who bore him a daughter Mudan. His second wife died a short time before the events in the story.
While on board the ship, Miss Marple found herself persuaded to take dancing lessons and was paired with Mr Pang. She appreciated this because he was short and stocky and this saved her the pain in her rheumatic neck from having to gaze up at her partner. While dancing, Mr Pang appeared to be startled by seeing something or somebody. Mr Pang had a life insurance policy with his children as beneficiaries. He was also rumoured to own a certain treasure. These formed the plausible motives for anyone wanting him dead. The next day he was found dead in his cabin. Unconvering what happened forms the main plot of the story.
