Perhaps you should try some spelling variations:
ky sang » ky nang, ky tang, duy sang
ky dang » ky nang, ky danh
hieu ve » hieu va, hieu van
va hanh » van hanh, va thanh, ban hanh
va danh » va dinh, va dan, dia danh
hoa cua » hoa chat, hoa xuat
cua tre » cua te, cuu tre, cua triet
ve cam » ve cham, ve cac, va cam

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

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