Perhaps you should try some spelling variations:
ban thanh » ban hanh, ban hang
ban tinh » quan tinh, ban hanh, bi tinh
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
cam luc » cam xuc, cau luc
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
ve cam » ve cham, ve cac, va cam
va chu » va che, va chi
va cau » van cau, va cac, va dau

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 ky nang xa hoi. hieu ve cam luc ((ban tinh) OR (ban thanh)) ((va chu) or (va cau)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang xa hoi. hieu ve cam luc ((ban tinh) OR (ban thanh)) ((va chu) OR (va cau)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang xa hoi. hieu ve cam luc ((ban tinh) OR (ban thanh)) ((va chu) or (va cau)) tre".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. hieu ve cam luc ((ban tinh) OR (ban thanh)) ((va chu) or (va cau)) tre*.
