Perhaps you should try some spelling variations:
chua tri » chu tri, chua trieu, chua tivi
chua tre » cua tre, chua trieu, cho tre
va hanh » van hanh, va thanh, va danh
ky tang » ky nang, ky dang, kho tang
hieu ve » hieu va, hieu van
hanh va » hang va, hanh vi
te sac » te sach, te cac, te san
xuc va » duc va, tuc va, luc va
sac ky » cac ky, sai ky
ma hoi » mai hoi, ma hoa, me hoi
ve cam » ve cham, ve cac, va cam

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: te sac ky tang ((ma hoi) OR (xa hoi)). hieu ve cam xuc va hanh va ((chua tre) OR (chua tri))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky tang ((ma hoi) OR (xa hoi)). hieu ve cam xuc va hanh va ((chua tre) or (chua tri))~".
• Adding a wildcard symbol may retrieve word variants: te sac ky tang ((ma hoi) OR (xa hoi)). hieu ve cam xuc va hanh va ((chua tre) or (chua tri))*.
