Perhaps you should try some spelling variations:
ban hanh » ban hang
cac loc » cac lop, cac toc, cac hoc
nang xa » nang x, nang ma, ang xa
hanh di » hanh vi, hanh de, hang di
mang xa » mang may, dang xay, mang cua
lang xa » lang ha, dang xay, lang van
loc ban » lo ban, hoc ban, coc ban
hieu ve » hieu va, hieu van
di cua » dai cua, doi cua, de cua
te sai » te tai, te bai, te lai
ve cac » va cac, vien cac
sai ky » sac ky
cua te » cua tu

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sai ky ((((nang xa) OR (mang xa))) or (lang xa)) hoi. hieu ve cac loc ban hanh di cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sai ky ((((nang xa) OR (mang xa))) OR (lang xa)) hoi. hieu ve cac loc ban hanh di cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sai ky ((((nang xa) OR (mang xa))) or (lang xa)) hoi. hieu ve cac loc ban hanh di cua te".
• Adding a wildcard symbol may retrieve word variants: te sai ky ((((nang xa) OR (mang xa))) or (lang xa)) hoi. hieu ve cac loc ban hanh di cua te*.
