Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
van hanh » van thanh, ban hanh, van anh
su triet » su viet, su tien, ve triet
te sach » toc sach
qua cam » qua cham, qua cac, qua ca
xuc van » duc van, luc van, vuc van
y nang » ky nang, ly nang, may nang
v nang » va nang, vu nang, van nang

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

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