Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hieu vien » hieu hien, hieu viec, thieu nien
thuc van » thuc vat, thuc dan, thuc va
cac thuc » cach thuc, cac thu, can thuc
vien cac » vien bach, vien dai, vien da
hang di » hang doi, hang dien, hang dich
hang vi » hang va, hanh vi, khang voi
so sanh » do sanh
v nang » va nang, vu nang, van nang
y nang » ky nang, ly nang, may 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 sanh ((y nang) OR (v nang)) xa hoi. hieu vien cac thuc van ((hang di) or (hang vi)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sanh ((y nang) OR (v nang)) xa hoi. hieu vien cac thuc van ((hang di) OR (hang vi)) cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sanh ((y nang) OR (v nang)) xa hoi. hieu vien cac thuc van ((hang di) or (hang vi)) cua triet*".
