Perhaps you should try some spelling variations:
doanh sang » doanh quang, doanh ban, doanh van
cua triet » cua viet, su triet, va triet
vay doanh » van doanh, ly doanh, voi doanh
cua tre » cua te, cuu tre, dua tren
tuc vay » tuc va, tu vay, tuc xay

ve cham » va cham, ve chat, ve chim
lang xa » lang ha, dang xay, lang van
vu cham » va cham, vu kham, tu cham

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sach y lang xa hoi. hieu ((ve cham) or (vu cham)) tuc vay doanh sang ((cua tre) OR (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y lang xa hoi. hieu ((ve cham) OR (vu cham)) tuc vay doanh sang ((cua tre) OR (cua triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y lang xa hoi. hieu ((ve cham) or (vu cham)) tuc vay doanh sang ((cua tre) OR (cua triet))*".
