Is it true that Xi' an's digestive tract census places benefit the people?

Really hungry. Xi' an digestive tract census quota is really certified and will not be faked. Xi 'an, referred to as "Gao", was called Chang 'an and Haojing in ancient times. It is the capital of Shaanxi Province, a sub-provincial city, a megacity, the core city of Guanzhong Plain urban agglomeration, and an important central city in western China determined by the State Council.
