Perhaps you should try some spelling variations:
ban thanh » ban hanh, ban hang
va thanh » gia thanh, va tinh, le thanh
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
tu sac » tu sach, tu cac, tu san
ve cua » le cua, de cua, te cua
cua te » cua tu
ve cac » va cac, vien cac
sac ky » cac ky, sai ky
ve cam » ve cham, va cam, ve cai

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 lang xa hoi. hieu ((ve cam) or (ve cac)) duc ((va thanh) OR (ban thanh)) ve cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky lang xa hoi. hieu ((ve cam) OR (ve cac)) duc ((va thanh) OR (ban thanh)) ve cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky lang xa hoi. hieu ((ve cam) or (ve cac)) duc ((va thanh) OR (ban thanh)) ve cua te*".
