Perhaps you should try some spelling variations:
cua triet » su triet, va triet
cua viet » ca viet, hoa viet, cua vat
hieu ve » hieu va, hieu van
cam duc » cam xuc, cao duc, pham duc
duc van » duc va, duc tan, duc manh
hanh de » hanh kem
hanh ve » hanh vi, hanh va, hanh kem
nang xa » nang x, lang xa, nang ma
ve cam » ve cham, ve cac, va cam
sai ky » sac ky
te sai » te tai, te bai, te lai

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sai ky nang xa hoi. hieu ve cam duc van ((hanh de) or (hanh ve)) ((cua triet) OR (cua viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sai ky nang xa hoi. hieu ve cam duc van ((hanh de) OR (hanh ve)) ((cua triet) OR (cua viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sai ky nang xa hoi. hieu ve cam duc van ((hanh de) or (hanh ve)) ((cua triet) OR (cua viet))".
• Adding a wildcard symbol may retrieve word variants: te sai ky nang xa hoi. hieu ve cam duc van ((hanh de) or (hanh ve)) ((cua triet) OR (cua viet))*.
