Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
van hanh » van thanh, ban hanh, van anh
te sach » toc sach
nang ma » tang ma, nang cao, mang may
sang ma » tang ma, sang tao, mang may
qua cam » qua cham, qua cac, qua ca
xuc van » duc van, luc van, vuc van
vi cua » vai cua, di cua

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y ((nang ma) OR (sang ma)) hoi. hieu qua cam xuc van hanh vi cua triet~".
• Adding a wildcard symbol may retrieve word variants: te sach y ((nang ma) OR (sang ma)) hoi. hieu qua cam xuc van hanh vi cua triet*.
