Spend some time early in the morning in Green Lake Park.  It is a very short walk from the Harbour Plaza Hotel in central Kunming.  Every morning the park fills with hundreds of elderly people engaging in all forms of activities: tai-chi, fan dancing, western-style line dancing, badminton, kite flying, croquet, playing musical instruments, mah jong, walking, jogging, cycling, etc.  There are great photo opportunities and they welcome tourists to join them in their activities.  It's a fun way to spend a few hours before or after breakfast and before starting whatever your tour plans are for the day.
