Perhaps you should try some spelling variations:
thien van » thi van
te sach » toc sach
nang xa » nang x, lang xa, nang ma
van cam » van nam, van lam, van cau
thuc va » thuc vat, thuc dan, thuc day
hanh va » hang va
chua te » cua te, chua tu, chua xe
y nang » ky nang, ly nang, v nang
luc va » duc va, tuc va, loc 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 y nang xa hoi. thien van cam ((luc va) or (thuc va)) ((hanh va) OR (hanh vi)) chua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang xa hoi. thien van cam ((luc va) OR (thuc va)) ((hanh va) OR (hanh vi)) chua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang xa hoi. thien van cam ((luc va) or (thuc va)) ((hanh va) OR (hanh vi)) chua te".
• Adding a wildcard symbol may retrieve word variants: te sach y nang xa hoi. thien van cam ((luc va) or (thuc va)) ((hanh va) OR (hanh vi)) chua te*.
