Perhaps you should try some spelling variations:
hieu viec » nhieu viec, hieu ve, sieu viet
viec cac » vien cac, viec cua, viec lam
hanh hai » thanh hai, nhanh hai, hanh tai
hang hai » hoang hai, hang tai, thanh hai
nang xa » nang x, lang xa, nang ma
cac xuc » cam xuc, cac nuoc, chat xuc
san ky » sang ky, dan ky, ban ky
xuc va » duc va, tuc va, luc 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 xuc va ((hanh hai) OR (hang 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 xuc va ((hanh hai) OR (hang 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 xuc va ((hanh hai) OR (hang hai)) cua te*".
