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