Perhaps you should try some spelling variations:
viec cac » vien cac, viec lam, viec va
hanh vai » hanh vi, hanh va, hanh tai
vai cua » dai cua, hai cua, lai cua
va hanh » van hanh, va thanh, va danh
tuc va » thuc va, truc va, tuc xa
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: vu ((san ky) or (dan ky)) nang x hoi. hieu ((viec cac) OR (viec cua)) tuc va hanh vai cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu ((san ky) OR (dan ky)) nang x hoi. hieu ((viec cac) OR (viec cua)) tuc va hanh vai cua tu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ((san ky) or (dan ky)) nang x hoi. hieu ((viec cac) OR (viec cua)) tuc va hanh vai cua tu*".
