Perhaps you should try some spelling variations:
hanh dong » anh dong, ha dong
su triet » su viet, su tien, ve triet
thi nang » thi cong, ki nang, thi hanh
hanh don » nhanh dong, hanh doanh, thanh dong
nang nam » dang nam, hang nam, nang lam
nam thuc » nam thuoc, am thuc, nam thu
thuc va » thuc vat, thuc dan, thuc day
te sach » toc sach
tu sach » thu sach, su sach, tu cach
x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) or (te sach)) ky nang x hoi. thi nang nam thuc va ((hanh don) OR (hanh dong)) su triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) ky nang x hoi. thi nang nam thuc va ((hanh don) OR (hanh dong)) su triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (te sach)) ky nang x hoi. thi nang nam thuc va ((hanh don) OR (hanh dong)) su triet".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (te sach)) ky nang x hoi. thi nang nam thuc va ((hanh don) OR (hanh dong)) su triet*.
