You can spend years lost in Chaoyang District and never get bored. There's plenty to do, but there are very few historic sights. Spend a morning shopping at Silk Alley Market or Panjiayuan Antiques Market (best on weekend mornings) and the afternoon cooling off at Ritan Park or Chaoyang Park, the latter a large and pleasant park with a lot of activities for kids. Next, head to one of the numerous bar streets for refreshments. If you like contemporary art, browse the galleries at 798 Art District. There are a number of nice cafés here as well.
