Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hanh lam » thanh lap, hanh kem, dinh lam
thu sac » thu sach, thu san, thu xac
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
duc van » duc va, duc manh, duc phan
hanh va » hang va, hanh vi
sac ky » cac ky, sai ky
va cam » va cham, va cac, va cao

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: thu sac ky nang xa hoi. hieu va cam ((duc van) or (duc tan)) ((hanh lam) OR (hanh va)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sac ky nang xa hoi. hieu va cam ((duc van) OR (duc tan)) ((hanh lam) OR (hanh va)) cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sac ky nang xa hoi. hieu va cam ((duc van) or (duc tan)) ((hanh lam) OR (hanh va)) cua triet*".
