In the past,the housing conditions were very poor.Most people lived in small houses with only one floor.Sometimes,several families shared one yard and several family members shared one small room.The bedroom could be the dining room at the same time.Now those old and small houses have turned into new buildings in the city.Most families have moved into new flats with several rooms,usually including enough bedrooms,a sitting room,a dining room,a kitchen,a toilet and a balcony.Most of these new flats have gas and tap water.Some of the new flats have central heating system.
