Shandong people will go to Shantou, Guangzhou for about half a month next week. They don't know the climate, temperature, culture and diet there. They have never been to the south. What should they pay attention to? There are also many northerners here in Shantou. Although the locals are more exclusive, it is because most of them are foreigners who do bad things, and now they will not say that they look down on people who speak Mandarin. There are all kinds of diets, so don't worry about habits. The weather is about ten or twenty degrees, and the humidity is very high. Maybe northerners will not be used to it. Just wear a thin long-sleeved shirt with a coat or a thin sweater in spring and autumn. As for law and order, it's ok. Be careful. It should be okay.
