Perhaps you should try some spelling variations:
thuat sach » thuat lanh, thuat san
thien van » thi van
hoc cac » hoc cao
nang xa » nang x, lang xa, nang ma
nam xuc » cam xuc, nam xua, nam thuc
va hanh » van hanh, va thanh, va danh
vai cua » dai cua, lai cua, bai cua
hai cua » thai cua, dai cua, hoi cua
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: ((thuat sach) or (hoc cac)) ky nang xa hoi. thien van nam xuc va hanh ((vai cua) OR (hai cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thuat sach) OR (hoc cac)) ky nang xa hoi. thien van nam xuc va hanh ((vai cua) OR (hai cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thuat sach) or (hoc cac)) ky nang xa hoi. thien van nam xuc va hanh ((vai cua) OR (hai cua)) tre".
• Adding a wildcard symbol may retrieve word variants: ((thuat sach) or (hoc cac)) ky nang xa hoi. thien van nam xuc va hanh ((vai cua) OR (hai cua)) tre*.
