vien cac » vien bach, vien dai, vien da
tuc van » thuc van, truc van, tuc va
hang vi » hang va, hanh vi, khang voi
hang di » hang doi, hang dien, hang dich
so sach » so sanh, bo sach, co sach
nang xa » nang x, lang xa, nang ma
y nang » ky nang, ly nang, v nang

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

• Performing a fuzzy search may retrieve terms with similar spellings: so sach y nang xa hoi. hieu ((hien cac) OR (vien cac)) tuc van ((hang di) or (hang vi)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach y nang xa hoi. hieu ((hien cac) OR (vien cac)) tuc van ((hang di) OR (hang vi)) cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach y nang xa hoi. hieu ((hien cac) OR (vien cac)) tuc van ((hang di) or (hang vi)) cua triet*".
