Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hieu van » hieu va, thien van, lieu va
van tham » van thanh, van tuan, van chat
tham xuc » tham nuoc, tham thuc, pham duc
nang xa » nang x, lang xa, nang ma
va danh » va dinh, va dan, va hanh
danh vi » hanh vi, dinh vi, danh di
cua tre » cua te, cuu tre, dua tren
can ky » dan ky, ban ky, tan ky
xuc va » duc va, tuc va, luc 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 ((can ky) OR (van ky)) nang xa hoi. hieu van tham xuc va danh vi ((cua tre) or (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((can ky) OR (van ky)) nang xa hoi. hieu van tham xuc va danh vi ((cua tre) OR (cua triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((can ky) OR (van ky)) nang xa hoi. hieu van tham xuc va danh vi ((cua tre) or (cua triet))*".
