I would choose Chinese cuisine, Japanese cuisine and Thai cuisine.
1. Chinese food is known for its diversity, only for hot pot, you can find more than five specific styles in different areas. I doubt if ten years are long enough or not to finish the food journey in China.
2. Japanese food is known for its healthy way of cooking and delicacy. So I think to take it as a main dish and eat for a long time is a good thing.
3. Thai food perfect matches my food taste, I like sour and spicy taste.
To taste local cuisine has always been an important part for me when I travel.
