Perhaps you should try some spelling variations:
su triet » su viet, su tien, ve triet
van hanh » van thanh, ban hanh, van anh
xuc van » duc van, luc van, vuc van
hoc sai » hoc bai, hoc tai, hoc hai
nang ma » tang ma, sang ma, nang cao
hoc dai » hoc dan
hieu ve » hieu va, hieu van
ma hoi » mai hoi, xa hoi, ma hoa
ve cam » ve cham, ve cac, va cam
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 sai) OR (hoc dai)) ky nang ma hoi. hieu ve cam xuc van hanh vi ((cua te) or (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc sai) OR (hoc dai)) ky nang ma hoi. hieu ve cam xuc van hanh vi ((cua te) OR (su triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc sai) OR (hoc dai)) ky nang ma hoi. hieu ve cam xuc van hanh vi ((cua te) or (su triet))".
• Adding a wildcard symbol may retrieve word variants: ((hoc sai) OR (hoc dai)) ky nang ma hoi. hieu ve cam xuc van hanh vi ((cua te) or (su triet))*.
