Perhaps you should try some spelling variations:
ban thanh » ban hanh, ban hang
duc ban » duc tan, duc van, dua ban
hai cuc » tai cuc, hai cua, thai cua
hai cuu » hai cua, hai chu, thai cua
nang xa » nang x, lang xa, nang ma
ve cac » va cac, vien cac
sac ky » cac ky, sai ky
va cam » va cham, va cac, va cao
su sac » su sach, su cac, su xac

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sac ky nang xa hoi. hieu ((va cam) or (ve cac)) duc ban thanh ((hai cuu) OR (hai cuc)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky nang xa hoi. hieu ((va cam) OR (ve cac)) duc ban thanh ((hai cuu) OR (hai cuc)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky nang xa hoi. hieu ((va cam) or (ve cac)) duc ban thanh ((hai cuu) OR (hai cuc)) tre".
• Adding a wildcard symbol may retrieve word variants: su sac ky nang xa hoi. hieu ((va cam) or (ve cac)) duc ban thanh ((hai cuu) OR (hai cuc)) tre*.
