Perhaps you should try some spelling variations:
thien van » thi van
cua triet » cua viet, su triet, va triet
van chat » cao chat
chat luc » chat xuc, chat lua, nhan luc
dua tren » dung tren
nang xa » nang x, lang xa, nang ma
va hanh » van hanh, va thanh, va danh
cua tre » cua te, cuu tre, cua thep
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
luc va » duc 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 hanh vi ((((cua tre) OR (dua tren))) 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 hanh vi ((((cua tre) OR (dua tren))) 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 hanh vi ((((cua tre) OR (dua tren))) or (cua triet))*".
