Mulberry orchard of Tiangong Manor is the largest mulberry base in Ningbo City. When Wu Zumei, secretary of Wandi Village, was inspired by mulberry planting in Israel, he began to adjust the agricultural planting structure after returning to Wandi Village and changed to mulberry planting, which once became the largest mulberry picking base in the country. The manor has introduced hundreds of mulberry fruit varieties to form a Baisang Garden viewing area and a fine picking area. Since 2004, the Mulberry Culture Festival of Tiangong Manor has been held every year, which has become a well-known festival activity around.

The varieties of mulberry fruit in the garden are mainly "big ten", and the output per square kilometer can reach 2000 kg, which is one of the top ten fine fruits in Ningbo in 2007. It has high sugar content, good color and good taste, each grain weighs about 3.5 grams, and is one of the top ten fine fruits in Ningbo City.
