Perhaps you should try some spelling variations:
dang mai » dang hai, dang mau, dang bai
ve triet » va trien, su triet
hoc mac » hoc ma, hoc may, hoc cac
ky dang » ky nang, ky danh
mai hoi » mai khoi, dai hoi, lai hoi
hieu ve » hieu va, hieu van
mac ky » cac ky, sac ky, bac ky
ve cam » ve cham, ve cac, va cam
xuc va » tuc va, luc va, xac va
cua te » cua tu

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

• If you are trying to use Boolean operators, they must be ALL CAPS: hoc mac ky dang mai hoi. hieu ve cam ((xuc va) OR (duc va)) hanh vi ((cua te) OR (ve triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc mac ky dang mai hoi. hieu ve cam ((xuc va) OR (duc va)) hanh vi ((cua te) or (ve triet))~".
• Adding a wildcard symbol may retrieve word variants: hoc mac ky dang mai hoi. hieu ve cam ((xuc va) OR (duc va)) hanh vi ((cua te) or (ve triet))*.
