Perhaps you should try some spelling variations:
doanh dan » doanh ban, doanh van, doanh dao
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
hieu va » lieu va
dan cua » dan ca, ban cua, dai cua
toc ta » toc tay, toc thai
te sai » te tai, te bai, te lai
toc va » hoc va, tuc va, loc va
sai ky » sac ky
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: te sai ky lang xa hoi. ((hieu va) OR (hieu qua)) cac ((toc va) OR (toc ta)) doanh dan cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sai ky lang xa hoi. ((hieu va) OR (hieu qua)) cac ((toc va) or (toc ta)) doanh dan cua te~".
• Adding a wildcard symbol may retrieve word variants: te sai ky lang xa hoi. ((hieu va) OR (hieu qua)) cac ((toc va) or (toc ta)) doanh dan cua te*.
