Nanjing and Qingdao are both famous tourist cities with rich tourist resources. Although Changsha has many scenic spots, it is not a tourist city, so it is not as good as Nanjing and Qingdao in tourism supporting construction and service.

The most important personal experience and play experience of tourism, compared with many ornamental attractions in Changsha, Qingdao is surrounded by mountains and seas, and tourism themes such as beaches and ocean parks are more immersive; Nanjing's scenic spots are the perfect combination of heavy history and modern urban sense, and the experience is more profound. Compared with the first two cities, the characteristics of Changsha are not obvious enough. But among the three, Changsha is better than Changsha. Nanjing and Qingdao have more specialties than vegetables, and Changsha has more street snacks.

Because the tourist reception volume is estimated according to the ticket purchasing information of passengers from different places in railway, aviation, passenger transport and other departments according to the proportional formula, Nanjing and Changsha, as important transportation hubs, have a much larger passenger reception volume than Qingdao, so the calculation result of tourist reception volume is naturally larger. Qingdao is located at the end of land transportation, with a large proportion of tourists.

In terms of tourism supporting resources, Qingdao's score is far ahead of Nanjing and Changsha, second only to Beijing, Chongqing and Shanghai, ranking fourth in the country, and it is the only non-municipality in the top five.

Of course, to feel the tourism strength of a city, personal style, preferences, age, season and luck are all very important. For example, you like the feeling of clear water and green mountains and a paradise. As a result, you went to Nanjing, one of the four stoves. It was so hot in the dog days, and then you happened to eat in an unpalatable and expensive restaurant. After a bad trip, you go back to the hotel and get angry with the waiter. Then you won't think Nanjing is good. On the contrary, you are a person who likes modern history and urban atmosphere. If you go to Nanjing in March and April, the temperature is comfortable in spring, there are not so many tourists, you can eat well, live well, have fun and have a low cost. Then you will definitely say that Nanjing is very good.

So travel is a large-scale life, and the choice of preferences and luck are very important. Every city has its own unique place. If you feel the beauty of a city with your heart, you will surely find something extraordinary about it. If you look at a city with a gloomy mind, then the city you see is useless.
