What is the price index of each city? For example, how much of Beijing's 100 yuan was spent in Chengdu and how much was spent in Urumqi?
I came to Beijing from Chengdu and compared the prices of the two places. I think the price of daily necessities (such as food) in Beijing is twice that in Chengdu. For example, a bowl of noodles in 3 yuan, Chengdu, and 6 yuan in Beijing. But it does not include things with technical content such as electronic products.
