Chang remained unmentioned in the stories until Tintin in Tibet, published almost 25 years later in 1958. In this story, Chang sends Tintin a letter in which he announces his imminent move from Hong Kong, where he had been living, to London in order to work in an antique shop owned by a brother of Wang's. His aeroplane, however, crashes over the mountains of Tibet. Chang survives the disaster while all his fellow passengers perish, and is rescued by the yeti, the mythical creature said to live in the Himalayas. The yeti takes care of Chang, providing him with food, but when rescue arrives, he also takes Chang, weak with fever, as far away as possible.
