Perhaps you should try some spelling variations:
thien van » thi van
cua triet » cua viet, su triet, va triet
te sach » toc sach
ky lang » ky nang, ky tang, tay lang
ky dang » ky nang, ky danh
nam xuc » cam xuc, nam xua, nam thuc
va danh » va dinh, va dan, va hanh
danh va » doanh va, hanh va, anh va
cua tre » cua te, cuu tre, dua tren
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 sach ((ky lang) or (ky dang)) xa hoi. thien van nam xuc va danh va ((cua tre) OR (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ky lang) OR (ky dang)) xa hoi. thien van nam xuc va danh va ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ky lang) or (ky dang)) xa hoi. thien van nam xuc va danh va ((cua tre) OR (cua triet))".
• Adding a wildcard symbol may retrieve word variants: te sach ((ky lang) or (ky dang)) xa hoi. thien van nam xuc va danh va ((cua tre) OR (cua triet))*.
