If you like quiet places, I only know that there are two places where I have never been to Telford Lane Bar, a street in the north gate of the old campus of the Outer Courtyard and a bar. It seems that many foreigners have never been to Telford Lane, where consumption should be high. There are many students and the price is relatively cheap. It seems that a dozen Budweisers are around 180, which should be almost the price of Xi 'an.
The price of nightclubs depends on what kind of wine you drink, but it will be more expensive if there are many people going to the right place. Not bad, about 600+. Fan Texi is the most expensive, but the environment is very good. I like the harem and have never been to Sasha. It's cheaper, but if you want to have a good time in Xi 'an, you really have to pay a lot of gold.
