Perhaps you should try some spelling variations:
kho tang » cao tang
cua tre » cua te, cuu tre, cua triet
tai cua » thai cua, tai cuc, tri cua
va danh » va dinh, va dan, va hanh
va xanh » va hanh, va anh, va banh
hieu ve » hieu va, hieu van
ky tang » ky nang, ky dang, ky trong
mai hoi » mai khoi, dai hoi, lai hoi
ve cam » ve cham, ve cac, va cam
vu sac » vu sach, vu san, va sac

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

• Performing a fuzzy search may retrieve terms with similar spellings: vu sac ((ky tang) or (kho tang)) mai hoi. hieu ve cam xuc ((va xanh) OR (va danh)) tai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sac ((ky tang) OR (kho tang)) mai hoi. hieu ve cam xuc ((va xanh) OR (va danh)) tai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sac ((ky tang) or (kho tang)) mai hoi. hieu ve cam xuc ((va xanh) OR (va danh)) tai cua tre*".
