Perhaps you should try some spelling variations:
doanh van » doan van, doanh va, doanh ban
xach tay » canh tay
sach tay » sach hay, sach nay, sach tai
va doanh » van doanh, vay doanh, va danh
van cua » vang cua, ban cua, dan cua
lang xa » lang ha, dang xay, lang van
ve chat » va chat, van chat
xuc va » duc va, tuc va, luc va
ve cam » ve cham, ve cac, va cam
cua te » cua tu

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: thu ((sach tay) OR (xach tay)) lang xa hoi. hieu ((ve cam) OR (ve chat)) xuc va doanh van cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach tay) OR (xach tay)) lang xa hoi. hieu ((ve cam) or (ve chat)) xuc va doanh van cua te~".
• Adding a wildcard symbol may retrieve word variants: thu ((sach tay) OR (xach tay)) lang xa hoi. hieu ((ve cam) or (ve chat)) xuc va doanh van cua te*.
