Perhaps you should try some spelling variations:
ban thanh » ban hanh, ban hang
cua triet » cua viet, su triet, va triet
thuy anh » thuy linh
hieu van » hieu va, thien van, lieu va
va thanh » gia thanh, va tinh, le thanh
vien cua » viec cua, dien cua, tien cua
nang xa » nang x, lang xa, nang ma
tu sac » tu sach, tu cac, tu san
nam tu » nam thu, nam thuc

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sac) or (thuy anh)) ky nang xa hoi. hieu van nam tu ((va thanh) OR (ban thanh)) vien cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sac) OR (thuy anh)) ky nang xa hoi. hieu van nam tu ((va thanh) OR (ban thanh)) vien cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sac) or (thuy anh)) ky nang xa hoi. hieu van nam tu ((va thanh) OR (ban thanh)) vien cua triet".
• Adding a wildcard symbol may retrieve word variants: ((tu sac) or (thuy anh)) ky nang xa hoi. hieu van nam tu ((va thanh) OR (ban thanh)) vien cua triet*.
