Among the teapot created by Xu, many pots are created for current events. At the beginning of 2009, he and the painter Jackie Lui planned, discussed and conceived the creation of Expo-themed purple sand works, and asked the painter Han Min to draw a picture of Laozi's Tea Tasting. Subsequently, Xu and his son Xu Zefeng led the disciples of Sihaiyao to create 18 gift jars for the Shanghai World Expo, which were appreciated by Chinese and foreign tourists during the Expo. It is reported that the whole set of Expo gift cans was taken away by collectors at an auction for 6.5438+0.8 million yuan.

He and Zhao Benshan became attached to tea five years ago, and they created the series of "Mountain and Sea Zisha Pots" hand in hand. Up to now, more than 30 kinds of "mountain and sea pots" have been created, two for each kind, one for Zhao Benshan and one for Xu. In the future, they will also launch 100 "mountain and sea pots" with novel styles and different shapes, each of which is made and painted by Xu himself and inscribed by Zhao Benshan. The two people work closely together, and each "mountain and sea pot" has the same signature of two people, and is equipped with a serial number certificate, so the collection value is self-evident.

Xu is not only a renowned master of Shanghai Zisha art at home and abroad, but also a legendary collector of ancient pots. In the Hayes Pot Hall he founded, more than 1000 pieces of teapot collected by him in Tang, Song, Yuan, Ming and Qing dynasties were exhibited. Among them, the treasure of the town hall "Daheng pot" was originally a family heirloom made by Shao Daheng specially for the Pan family in Yixing. Surprisingly, the pot drifted from one place to another with its owner without any damage. Later, the Pan family was short of money to build a house and was ready to sell the tycoon pot. After hearing the news, Xu, who is participating in the creation of Yixing Zisha Craft Factory, discussed with his wife Jin and rushed to Panjia to see the pot. After going through all kinds of hardships, he bought the tycoon's pot for 30 thousand yuan, which was not a small sum in the 1980 s Gu Jingzhou, a master of purple sand, spoke highly of the tycoon pot. He also made a special trip to Xu's home and offered to have a look at the tycoon's pot. This is Gu Jingzhou's last trip to Shanghai.
