Where is the quadrangle of Nantong Port Gate?

Nantong Gangzha Courtyard is as follows:

1, Chen's study. Chen Garden was founded in the late Qing Dynasty by Chen, a famous industrialist in Nantong in modern times. Expanded by his son Chen Baochu, it once occupied more than 30 hectares. This building is the reading room for its descendants. It was built in the Republic of China and is located in Chen Garden (now Green Valley of the City). It is a resting peak with three colonnades, the width of three rooms, the depth of two columns and a mixed structure of brick, wood and concrete. It is the representative of modern traditional architecture in Nantong.

2. Fuxing Lane 1 Lane No.8 Residential Building, built during the Republic of China, is a quadrangle consisting of a main building and a gatehouse. The main building is a two-story brick-wood structure, with two floors wide and four boundaries deep. The roof truss is a bucket-through structure, with black butterfly tile roof, three-line roof and cat's head cornice. After several years' maintenance, the building has retained the original spatial pattern and most of the wind-proof walls, and it is the representative of modern residential buildings in Gangmen.

3. Gu Yayan's former residence is located in residential buildings at No.57 and No.58 Hedong North Road. Gu Yayan's former residence was built in the late Qing Dynasty and early Republic of China. There are two roads and three entrances in the whole courtyard. There are wings on both sides of the courtyard, two-story brick-wood buildings facing the street and fair-faced brick walls. The peaks of Guanyin sinus are quite distinctive. The main building faces south, which is a typical hard mountain structure with three bright faces and five dark faces.
