Perhaps you should try some spelling variations:
thien van » thi van
cua triet » cua viet, su triet, va triet
van chat » cao chat
nang xa » nang x, lang xa, nang ma
cua tre » cua te, cuu tre, dua tren
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
luc 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: tu sac ky nang xa hoi. thien van chat ((luc va) OR (duc va)) hanh vi ((cua tre) or (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang xa hoi. thien van chat ((luc va) OR (duc va)) hanh vi ((cua tre) OR (cua triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang xa hoi. thien van chat ((luc va) OR (duc va)) hanh vi ((cua tre) or (cua triet))*".
