Perhaps you should try some spelling variations:
viec cac » viec cua, viec lam, viec va
vien cac » vien bach, vien dai, vien da
hanh hai » thanh hai, nhanh hai, hang hai
hai cua » thai cua, dai cua, hoi cua
sang ky » sang kyo, dang ky, tang ky
lang xa » lang ha, dang xay, lang van
va hanh » van hanh, va thanh, va danh
luc va » duc va, tuc va, loc va
san ky » van ky, dan ky, ban 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: vu ((san ky) OR (sang ky)) lang xa hoi. hieu ((viec cac) or (vien cac)) luc va hanh hai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu ((san ky) OR (sang ky)) lang xa hoi. hieu ((viec cac) OR (vien cac)) luc va hanh hai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ((san ky) OR (sang ky)) lang xa hoi. hieu ((viec cac) or (vien cac)) luc va hanh hai cua te*".
