Introduction to the century-old grape vine: The century-old grape vine is located in the side yard and the middle courtyard of the main area. It was planted in the early years of Qianlong in the Qing Dynasty. It has a history of more than 260 years. The fruit is exquisite and seedless and has a sweet taste. Although it has gone through hundreds of years of vicissitudes, it still remains the same. The branches are luxuriant and the leaves are luxuriant. Every summer and autumn, the fruits are abundant, which makes people salivate. A ten-day grape festival is held here every year at the end of July, allowing tourists to taste it for free.
