Zhang Tianji, the builder of He Fang Pavilion, was not married at the age of 38. Su Shi was willing to intercede for Zhang and find a suitable woman for him, but Zhang Wanyan declined.

Zhang Tianji said that it is better to adhere to the Taoist celibacy life of "learning to keep in good health and taking thousands of breaths at once". In this way, Zhang Tianqi has been living a life of "plum wife crane" in the crane pavilion. It can also be seen that Zhangshan people are addicted to the art of "cultivating truth and cultivating nature".

The friendship between Su Shi and Zhang Tianji lasted for a long time. 12 years later, that is, 1089, when Su Shi was appointed as the magistrate of Hangzhou, Zhang Tianji had not traveled thousands of miles to visit him in Hangzhou. Su Shi warmly entertained his old friend and stayed for 10 days before sending him a farewell poem.
