Perhaps you should try some spelling variations:
ky dang » ky nang
ky danh » ky anh
xay hoi » xa hoi, tay hoi, cay phoi
hieu ve » hieu va, hieu van
va hanh » van hanh, va thanh, va danh
cua tre » cua te, cua triet, dua tren
cuu tre » cau tren, cau treo
ve cam » ve cham, ve cac, va cam
xuc va » duc va, tuc va, luc va

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

• Performing a fuzzy search may retrieve terms with similar spellings: te tai ((ky dang) or (ky danh)) xay hoi. hieu ve cam xuc va hanh vi ((cua tre) OR (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te tai ((ky dang) OR (ky danh)) xay hoi. hieu ve cam xuc va hanh vi ((cua tre) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te tai ((ky dang) or (ky danh)) xay hoi. hieu ve cam xuc va hanh vi ((cua tre) OR (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: te tai ((ky dang) or (ky danh)) xay hoi. hieu ve cam xuc va hanh vi ((cua tre) OR (cuu tre))*.
