Perhaps you should try some spelling variations:
thien van » thi van
vu khach » vu khanh, vu khac, vay khach
hanh lai » hanh lam, hanh tai, thanh lap
van cac » van hac, van cau, van bac
cac xuc » cam xuc, cac nuoc, chat xuc
va hanh » van hanh, va thanh, va danh
y lang » o lang, tay lang, yen lang
_ lang » o lang, _ land
xuc va » duc va, tuc va, luc va
cua tu » cua tuc, cua su, cua te
cua cu » cua chu, cua cau, cua su

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

• If you are trying to use Boolean operators, they must be ALL CAPS: vu khach ((y lang) OR (_ lang)) xa hoi. thien van cac xuc va hanh lai ((cua tu) OR (cua cu))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu khach ((y lang) or (_ lang)) xa hoi. thien van cac xuc va hanh lai ((cua tu) OR (cua cu))~".
• Adding a wildcard symbol may retrieve word variants: vu khach ((y lang) or (_ lang)) xa hoi. thien van cac xuc va hanh lai ((cua tu) OR (cua cu))*.
