Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
cau theo » cau thi, cau tao
van hang » van khang, van hoang, van thang
xuc van » duc van, luc van, vuc van
hang di » hang doi, hang vi, hang dien
te sach » toc sach
hieu ve » hieu va, hieu van
y nang » ky nang, ly nang, may nang
v nang » va nang, vu nang, van nang
ve cam » ve cham, ve cac, va cam

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 ve cam xuc van hang di ((cua triet) or (cau theo))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((y nang) OR (v nang)) xa hoi. hieu ve cam xuc van hang di ((cua triet) OR (cau theo))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((y nang) OR (v nang)) xa hoi. hieu ve cam xuc van hang di ((cua triet) or (cau theo))*".
