Guangdong soup is delicious. At least I, a Hunan native, like it. I think most people will like it, because it doesn't need to be very spicy. Guangdong Laohuo Health Soup is good for tonifying kidney. It depends on the skill of the chef. Just don't make soup with strong wolfberry flavor. If you entertain Hunan guests, you'd better not choose Cantonese food that is too sweet. Some dishes are slightly spicy, and authentic Cantonese dishes should also be available, mainly fresh. In fact, don't care too much, just ordinary.
By the way, when you say guests, do you mean good friends or something? In that case, you'd better eat more spicy food. If you are an important guest, if you want to talk about something, you'd better not make it too spicy, because it's too spicy, red in the face and runny nose, which is not good-looking. I mean, don't deliberately ask for spicy food to cater to the tastes of those guests.
I hope I can help you.
