Perhaps you should try some spelling variations:
cua triet » cua viet, su triet
thien van » thi van
va triet » va thiet, va trien, ve triet
hanh tai » thanh tai, hang tai, han tai
hanh dai » hanh dao, vanh dai, thanh dat
van cham » van chat, van tham, va cham
nang xa » nang x, lang xa, nang ma
soc va » hoc va, loc va, doc va
sai ky » sac ky
tu sai » tu bai, tu san, tu cai

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 ((hanh dai) OR (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 ((hanh dai) OR (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 ((hanh dai) OR (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 ((hanh dai) OR (hanh tai)) ((cua triet) or (va triet))*.
