Perhaps you should try some spelling variations:
van hanh » van thanh, ban hanh, van anh
hanh cat » hanh cac, hanh luat, nhanh cay
nang xa » nang x, lang xa, nang ma
xuc van » duc van, luc van, vuc van
cat cua » chat cua, ca cua, mat cua
san ky » sang ky, van ky, ban ky
dan ky » van ky
ve cai » va cai, ve cac, ve tai
cua te » cua tu
hien » bien, vien, tien

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu ((san ky) OR (dan ky)) nang xa hoi. hieu ((ve cai) or (hien dai)) xuc van hanh cat cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((san ky) OR (dan ky)) nang xa hoi. hieu ((ve cai) OR (hien dai)) xuc van hanh cat cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((san ky) OR (dan ky)) nang xa hoi. hieu ((ve cai) or (hien dai)) xuc van hanh cat cua te*".
