Before they became "celebrity cities on the Internet", Chongqing, Chengdu and Xi had a good reputation and were the cities that many people yearned to live in. In other words, they have become "network celebrity cities" by virtue of their "network celebrity physique". To say which city is the most livable, Chongqing, Chengdu or Xi, I think we need a concrete analysis. This is not a general answer. So I will simply talk about why from different angles. 1, different scenery. Many places people visit in Chengdu and its surrounding tourist attractions are basically naturally formed, such as Dujiangyan, Jiuzhaigou and Huanglong in western Sichuan, and of course, the giant panda breeding base in China, which are very attractive reasons to go to Chengdu; In Chongqing, we can see more revolutionary marks. We can find the hardships of War of Resistance against Japanese Aggression and the happy life now. Xi 'an, the ancient capital of the Six Dynasties, saw more historical marks in Xi 'an and a very important part of China's long history, such as the Terracotta Warriors and Horses, Xi 'an ancient city wall and so on. All these can show the rich history of our country. 2. The food is different. Speaking of tourism, the last thing people can't ignore is food. Chengdu and Chongqing are not far apart and geographically close, so their diets are similar and spicy, which is what they have in common, but there are still great differences. Generally speaking, Chengdu is hemp and Chongqing is spicy, which can be illustrated by the famous hot pot in the two places. But it seems that there are many kinds of snacks in Chengdu. Xi' an is located in the northwest, mainly stewing, stewing and boiling, and mainly pasta. Generally speaking, there is no pepper in the dish, but it is not greasy, but this does not mean that Xi people don't eat spicy food. One of the eight eccentrics in Shaanxi is "a dish of spicy oil", and a bowl of spicy oil and a steamed bread can also be delicious. Xi's most representative foods are mutton buns and biangbiang.
