Many people in China now own their own homes.  Almost every home is in an apartment complex.  China has about the same size of land as America, but more than 6 times the population.  There is simply not enough space to build separate houses.  The apartment complexes are built higher and higher.  It used to be 2 to 3 stories.  Now you will find many 10 to 20 story apartments.  Only those higher than 7 stories are equipped with elevators.  Imagine you live on the 6th floor and have to go out 4 times per day on average.  Who needs to walk on a treadmill living there, not to say that the bus stop or farmer’s market is at least 200 yards away?

My sister’s family lives in a four-bed room apartment with 1200 square feet.  I included the pictures showing the outside and the living room.
