Perhaps you should try some spelling variations:
ban thanh » ban hang
ban hanh » ban hang
nang xa » nang x, lang xa, nang ma
dau luc » cau luc, dau luan, dau nuoc
doi cua » dai cua, hoi cua
cua tre » cua te, cuu tre, cua triet
su sac » su sach, su cac
su xac » pu xac, su cac
va dau » va dao

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((su sac) or (su xac)) ky nang xa hoi. lieu va dau luc ((ban thanh) OR (ban hanh)) doi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sac) OR (su xac)) ky nang xa hoi. lieu va dau luc ((ban thanh) OR (ban hanh)) doi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sac) or (su xac)) ky nang xa hoi. lieu va dau luc ((ban thanh) OR (ban hanh)) doi cua tre".
• Adding a wildcard symbol may retrieve word variants: ((su sac) or (su xac)) ky nang xa hoi. lieu va dau luc ((ban thanh) OR (ban hanh)) doi cua tre*.
