Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh van, thanh tai
hieu viec » nhieu viec, hieu ve, sieu viet
viec cac » vien cac, viec cua, viec lam
vai cua » dai cua, hai cua, lai cua
tuc va » thuc va, truc va, duc va
san ky » sang ky, van ky, ban ky
dan ky » van ky
cua tu » cua tuc, cua su, cua cu
x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: va ((san ky) OR (dan ky)) nang x hoi. hieu viec cac ((tuc va) or (tuc xa)) thanh vai cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: va ((san ky) OR (dan ky)) nang x hoi. hieu viec cac ((tuc va) OR (tuc xa)) thanh vai cua tu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "va ((san ky) OR (dan ky)) nang x hoi. hieu viec cac ((tuc va) or (tuc xa)) thanh vai cua tu*".
