You can bring local ornaments and bracelets, which you can't buy in other places. Don't go to see the story of stone, it is popular all over the country.
Or something that you can DIY with your girlfriend.
You can also buy some beautiful clothes with local characteristics. Of course, the choice of clothes should be based on your girlfriend's preferences.
You can also go to the local people's home and ask if there is anything special for your lover, which is very memorable.
You can also buy a bag of sour plum powder to cool off the heat in summer. When you give it to your girlfriend, don't forget to say: I'll give you a summer vacation, idiot.
Well, that should be it. I hope it helps you, (* _ _ *)
