At that time, people's clothes were very simple in style, fabric and color although people's living standards had gradually improved since the establishment of Inner Mongolia autonomous region in 1947.

A photo shows clothing coupons, also known as bupiao, a product of China's planned economy from decades ago. Due to the tension between supply and demand, people had to use clothing coupons to buy cotton, boots, long underwear and even the threads that they used for sewing. A piece of clothing could be worn for years with regular sewing repairs. [Photo/ saibeinews.com]
