A friend went to Hong Kong before, he said: "I wondered, Hong Kong such a good place is actually dark, everywhere is spotless, clean and tidy, even the vegetable market is so clean, I didn't see that the sprinkler road and car are not dusty, really not comparable to mainland cities, unique and irreproducible internationalization, strong sense of city, Chinese and Western cultural blending, charming buildings and markets, open and free, very civilized, I have been to many big cities in the mainland, but none of them have the feeling of Hong Kong. Hong Kong is very pyrotechnic, Hong Kong barrier-free facilities, pedestrian bridge design, quite humane, rainproof and sunproof, pedestrian bridge directly connected with the shopping mall, convenient life everywhere is small supermarkets, bookstore restaurants, fruit stores, etc. quite a lot, life is super convenient. ”
