This is a whole area of heritage of Guangzhou, where you can see what traditional Guangzhou used be.
Besides cute YongQingFang street, the Bruce Lee's family mansion was really worth visiting, also visit the Cantonese Opera museum, it's colourful and so interesting!
Oh and the Li Zhi Wan Park down the street is just stunning, with a lake and water way around it, you can take a scenic boat from one end to the other of this area, in the park every afternoon from 2-5 they offer live Cantonese opera performance at the stage, its a must see!
In this area there a lots of Cantonese foods from full restaurants to street vendors, a hand grounded sesame soup dessert is a must try. Right beside the park there is one of the best vegan restaurant in town, first floor serves buffet and second floor severs Zen style a la carte.
Also check out the Xi Guan museum which shows a lot of curtail and history. Check out the RenWei temple too.
