You are from Guangdong and your father works in Dongguan, so you still know something about the climate and diet there. Cantonese food tastes sweet and light, and rice noodles are acceptable. Huainan is the staple food. When you come to Huainan, you should pay attention to your diet, because Huainan people not only like to eat, but also like spicy food, which is completely contrary to your taste. My advice to you: don't go to the small restaurants on the street (we also call some roadside restaurants food stalls in summer), because most of the small restaurants in Huainan are spicy. I think it may be because the chef's cooking is not good, so the dish is made like this, leaving only the taste of monosodium glutamate and pepper in his mouth. Over time, Huainan people became accustomed to it and naturally developed this taste. There are few fast food restaurants here, because there are no people who need to eat out. Most of them go home for dinner after work at noon, go to work in the afternoon, or the canteen of the enterprise. There are few restaurants on East Road, but I don't go to West Road much, but there seems to be a national noodle restaurant chain. If you work in the middle road, close to the city center, you will have a choice. There are many places to eat there. Because of your taste, let me help you choose some that suit you. The first choice is "daily health porridge", because the diet inside is close to the south, or that kind, with pasta and rice. Next to the health porridge, there is a "red tea house" that has been open for many years. Its signboard used to be "Clay Pot Rice", and it is now, but it is eaten too much, but according to your taste, a clay pot rice and a green vegetable are the most suitable. There is really no other choice, such as McDonald's, KFC, Pizza Hut and so on. But if you are looking for takeout, it will be very difficult. Probably running errands to fill the stomach, but there is nothing wrong with it. After eating, it is easy to digest. If it is the other way, I suggest you ask your colleagues. After all, you can't do it alone. If you come, you have to blend in.
Huainan is very hot in summer, but it is still worse than Guangdong. The highest is 37, who also wears shorts and short sleeves. The dust here is heavy and the air is not good. After all, there are coal mines and several coal-fired power plants. If you come to work for a long time, and it's autumn and winter, you can take the quilt with you (I suggest you buy it when you come) because it's not as cold as Guangdong. There is no winter there, so the coldest thing is probably a thick sweater, but if it is cold here, it can reach below zero, and you will only wear more than us.
Dialect is ok, much clearer than Cantonese. I don't understand a word of Cantonese. You may encounter some words you don't understand, but they are basically not difficult to understand, and they are still very partial to Mandarin. I go to school in Nanchang, and my classmates let me speak my hometown dialect. After listening to it, they all said that what I said was not authentic. Maybe it's because I lived in the city since I was a child. Dialect is not very heavy. What really matters is that I don't understand some of them myself.
In short, I hope my answer can help you, but you still have to get used to it yourself. Good luck!
