Perhaps you should try some spelling variations:
hieu viec » nhieu viec, hieu ve, sieu viet
viec cac » vien cac, viec cua, viec lam
va danh » va dinh, va hanh, dia danh
vai cua » dai cua, hai cua, lai cua
sang ky » sang kyo, dang ky, tang ky
lang xa » lang ha, dang xay, lang van
cac loc » cac lop, cac toc, cac hoc
va dan » ca dan, va dao, va dau
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 loc ((va danh) OR (va dan)) vai 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 loc ((va danh) OR (va dan)) vai 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 loc ((va danh) OR (va dan)) vai cua te*".
