Perhaps you should try some spelling variations:
trinh ve » trinh va, trinh vi, trinh viet
trinh he » trinh han, trinh hoa, trinh thi
su triet » su viet, su tien, ve triet
so sach » so sanh, bo sach, co sach
sach ky » sac ky, sach y, sach ty
nang ma » tang ma, sang ma, nang cao
tinh vi » trinh vi, tinh voi, tinh va
ma hoi » mai hoi, xa hoi, ma hoa
va cam » va cham, va cac, va cao
xuc va » duc va, tuc va, luc va

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: so sach ky nang ma hoi. lieu va cam xuc va ((tinh vi) or (((trinh ve) OR (trinh he)))) su triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ky nang ma hoi. lieu va cam xuc va ((tinh vi) OR (((trinh ve) OR (trinh he)))) su triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ky nang ma hoi. lieu va cam xuc va ((tinh vi) or (((trinh ve) OR (trinh he)))) su triet*".
