She is Ly Binh Nhi (lives in ward 3, Bac Lieu city), student of Vo Thi Sau Secondary School (currently she is 10 grade student of specialized chemistry,  Bac Lieu High School, Bac Lieu Province).

Nhi accessed internet to find the folk material can chase mosquitoes and she knew outside of tea residues there are tangerine and grapefruit peels. Getting these ideas, she went around to collect tangerine and grapefruit peels and tea residues dried, crushed, but she did not know how to glue.

Nhi gave her products for her friends and neighbors to use and add the survey form, suddenly she got good results, even some people asked for buying products because the incense is burned the mosquitoes run away, smoke smells very pleasant herb.
