I forgot to mention our trip to People's square park a couple of days ago. As Syd mentioned the paths were lined with older people sitting behind an umbrella on the ground. We are talking hundreds of people and hundreds of umbrellas. On each umbrella was posted a description of a person. Their height, age, occupation, etc...  I've read about this before but its essentially parents looking for spouses for their kids. Syd said though that some of the ads were for much older people so I guess in some cases it was parents or grandparents looking for someone for themselves. I'm not sure if this is every weekend in the park or if we just got lucky to see it.  We also saw a children's amusement park. Coolest activity in the park was  pond full of gold fish. For a few dollars you can rent a fishing pole and catch gold fish to take home as pets. Way better than a pet shop. I saw one little boy happily walking home with a little plastic aquarium stuffed with gold fish.
