Let's just say that the outdoor somatosensory sensation in Guangzhou at the end of April and the beginning of May is similar to that in Wuhan in midsummer. The coldest time in Guangdong is a little better than winter in Wuhan, so the climate is really not what you have to worry about.
Now Wuhan's economy is worse than Guangzhou's, but if you really come here, you will find that the gap is not as big as you think. Wuhan, founded in the Three Kingdoms period, is the first municipality directly under the central government in the history of China. For a long time, its overall strength was only behind Shanghai in China, and it gradually declined after being merged into Hubei Province, so the quality of real citizens was still good. Of course, ordinary citizens are everywhere. Please forgive me if you meet them.
Swearing in Wuhan is just a mantra, which is equivalent to exclamations. Few people really swear subjectively. Generally speaking, the traditional Wuhan people dare to love and hate, but they are not so barbaric. And Wuchang people are different from Hankou people. Wuchang is a cultural district, so Wuchang people are relatively low-key and introverted, and Hankou is a traditional business district, so Hankou people are relatively impetuous and enlightened, and South China University of Technology is in Wuchang:)
Besides, a good university will have exchanges and collisions of various languages and cultures, not only with Wuhan natives, but also with people from all over the country. Maybe you will find that students in Wuhan may be closer to your idea:)
Finally, if you choose to study in South China University of Technology, you should not feel unaccustomed, because the campus environment of South China University of Technology is clean and comfortable, and there is Lu Xiang next to South China University of Technology, which should be similar to Tianhe District, with dense universities, relatively new business districts, computer cities and subway stations. If you are interested, you can take the subway to Wuhan. Wuhan's diet is diversified, with sweet, salty, light and spicy snacks, and the variety is quite rich, just like Guangzhou. Many ancient buildings have been preserved. I believe that if you stay in Wuhan for four years or more, you will always remember this place. I once saw many middle-aged Cantonese with glasses and a good knowledge of Wuhan snacks in Hubu Lane, Wuhan, taking their families to visit. Maybe in a few years, you will become one of them:)
