Zheng Jia Da House is Zheng Guanying's house. It was once the scene of "rouge buckle". It is said that the window near the outside road is the best representative of the remaining Qing Dynasty residential courtyards in Macau. There are not only strong Lingnan characteristics, but also western traces. The combination of China and the West has a high humanistic value. To put it plainly, it's an enviable mansion.
