Perhaps you should try some spelling variations:
thien van » thi van
cua triet » cua viet, su triet
va triet » va thiet, va trien, ve triet
van cham » van chat, van tham, va cham
hanh tai » thanh tai, hang tai, han tai
nang xa » nang x, lang xa, nang ma
tu sai » tu bai, tu san, tu cai
loc va » hoc va, luc va
sai ky » sac ky
soc va » hoc va, doc va, goc 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 sai ky nang xa hoi. thien van cham ((soc va) or (loc va)) hanh tai ((cua triet) OR (va triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sai ky nang xa hoi. thien van cham ((soc va) OR (loc va)) hanh tai ((cua triet) OR (va triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sai ky nang xa hoi. thien van cham ((soc va) or (loc va)) hanh tai ((cua triet) OR (va triet))".
• Adding a wildcard symbol may retrieve word variants: tu sai ky nang xa hoi. thien van cham ((soc va) or (loc va)) hanh tai ((cua triet) OR (va triet))*.
