Perhaps you should try some spelling variations:
van thanh » ban thanh, van tuan
cua triet » cua viet, su triet, va triet
thanh de » hanh de, thanh ve, thanh do
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
cau luc » cau phuc
cua tre » cua te, cuu tre, dua tren
te sai » te tai, te bai, te lai
sai ky » sac ky

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sai ky nang xa hoi. hieu va ((cau luc) or (cau truc)) van thanh de ((cua tre) OR (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sai ky nang xa hoi. hieu va ((cau luc) OR (cau truc)) van thanh de ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sai ky nang xa hoi. hieu va ((cau luc) or (cau truc)) van thanh de ((cua tre) OR (cua triet))".
• Adding a wildcard symbol may retrieve word variants: te sai ky nang xa hoi. hieu va ((cau luc) or (cau truc)) van thanh de ((cua tre) OR (cua triet))*.
