Perhaps you should try some spelling variations:
thanh moi » thanh loi, thanh hoa, thanh hai
thanh doi » thanh loi, thanh do, thanh hoai
cuu tre » cua tre, cau tren, cau treo
luc ban » duc ban, cuc ban, luc bat
dau luc » cau luc, dau luan, dau nuoc
nang xa » nang x, lang xa, nang ma
va dau » va dao
pu xac » su xac
su sac » su sach, su cac, su xac

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