Perhaps you should try some spelling variations:
nhieu viec » hieu viec, nhien viet
cau treo » cau theo, cau tren, cau triet
danh vai » danh sai, danh va, doanh van
viec cac » vien cac, viec cua, viec lam
nang xa » nang x, nang ma, mang xa
lang xa » lang ha, dang xay, lang van
vai cau » va cau, van cau, vai cac
sac ky » cac ky, sai ky
co van » cao van, vo van, do van
so van » su van, vo van
te sac » te sach, te cac, te san

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sac ky ((nang xa) OR (lang xa)) hoi. nhieu viec cac ((co van) or (so van)) danh vai cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky ((nang xa) OR (lang xa)) hoi. nhieu viec cac ((co van) OR (so van)) danh vai cau treo*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky ((nang xa) OR (lang xa)) hoi. nhieu viec cac ((co van) or (so van)) danh vai cau treo*".
