How many coconuts can I take home when I go to Hainan, and what other fruits can I take home?

I lived in Hainan for four years. My experience is, don't bring coconut. First of all, because it is very heavy, there are usually five in the area, and you will cry on the road. Secondly, if you have to bring it, please bring a golden coconut (the kind whose shell can be carved with coconut). Don't buy red coconuts at roadside stalls. Red coconuts are found all over the country, with one in 5 yuan. It's not worth taking all the way home.

Mangosteen and durian are fruits from Taiwan Province Province, not from Hainan. It's up to you whether you bring them or not.

Jackfruit is sweet and stinks. The individual is large (twice as large as durian) and is not suitable for transportation. If you take half of them, they will go bad easily.

Litchi, longan and mango are probably available in your supermarket.

It is recommended to bring some small specialties that you can't buy in other places: passion fruit (sweet and sour), yellow peel (small and sweet), egg fruit (taste like egg yolk) and lotus mist (red and light).
