Perhaps you should try some spelling variations:
ve triet » va trien, su triet
cac xuc » cam xuc, cac nuoc, chat xuc
hieu ve » hieu va, hieu van
hoc sac » hoc sach, hoc cac, hoc mac
nang ma » tang ma, sang ma, nang cao
va danh » va dinh, va hanh, dia danh
ma hoi » mai hoi, xa hoi, ma hoa
ve cac » va cac, vien cac
sac ky » cac ky, sai ky
va dan » ca dan, va dao, va dau
cua te » cua tu

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

• Performing a fuzzy search may retrieve terms with similar spellings: hoc sac ky nang ma hoi. hieu ve cac xuc ((va danh) OR (va dan)) vi ((cua te) or (ve triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc sac ky nang ma hoi. hieu ve cac xuc ((va danh) OR (va dan)) vi ((cua te) OR (ve triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc sac ky nang ma hoi. hieu ve cac xuc ((va danh) OR (va dan)) vi ((cua te) or (ve triet))*".
