The consumption level in Beijing should be high. I have been to some other places, but the necessities of life are similar. For example, the prices of things like rice, oil and salt are almost the same, while the prices of other dispensable Beijing are higher, such as drinks, popsicles and beer. If you eat it, it depends on whether you cook it yourself or eat it out. It depends on the region anyway. According to Beijing, the Second Ring Road is higher than the outside of the Second Ring Road and the Third Ring Road is higher than the outside of the Third Ring Road. For example, the same dish of rice, 6 yuan outside the Third Ring Road, 8 yuan inside the Third Ring Road and 10 yuan inside the Second Ring Road. Supermarkets are mainly supermarkets that have never been to other places. I don't know what the difference is, it should be similar to the necessities of life, and everything else is expensive. If you travel by traffic, you'd better not take a taxi, and get a Beijing bus card. The one-way ticket is only 40 cents, which is not very expensive. In contrast, taking a taxi is not worth it. The starting price is1one kilometer in 2 yuan, 0 yuan. There is a traffic jam in Beijing, so it is better to travel by bus and subway. Now because of this, many taxi drivers in Beijing say they are going to lose their jobs. This problem is in Beijing Communication Radio (103.9). Renting is also divided into regions, ranging from 2000 to 3000 to 200 to 300 a month. Generally, you can find cheaper houses in the urban-rural fringe of Beijing, such as Haidian Chaoyang and other places. It's hard to say how much you can spend a month. It depends on many factors, such as rent, meals and travel. And in some places, houses have to pay utilities, and in some places, they don't have to pay. It's hard to say. Anyway, the average person in Beijing is about 1 10,000 a month. I don't know if it's from other places, for reference. As for the documents, that's all, plus the ID card. Seriously, if he really wants to drive people away, any certificate is useless. For example, in some areas where foreigners are concentrated before the Olympic Games, the police need temporary residence permits when they meet people. Tear them up when they come and ask them to apply for a temporary residence permit. They must have left at this time, because they just let him tear them up, so they will take them away. Therefore, this is to be prepared by yourself. Nothing else. Anyway, if it is possible to live with friends or find someone to share a better room, such a thing will not happen.
