Perhaps you should try some spelling variations:
phuc dong » phu dong, phuc khong, phuc trong
thuc dong » thuoc dong, thuc dung, thu dong
thanh do » thanh de, thanh pho, thanh hoa
ve nham » ve nha, ve cham
so sach » so sanh, bo sach, co sach
hieu ve » hieu va, hieu van
nang xa » nang x, lang xa, nang ma
te sach » toc sach
do cua » doi cua, co cua, de cua
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: ((so sach) OR (te sach)) ky nang xa hoi. hieu ve nham ((thuc dong) OR (phuc dong)) thanh do cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so sach) or (te sach)) ky nang xa hoi. hieu ve nham ((thuc dong) OR (phuc dong)) thanh do cua te~".
• Adding a wildcard symbol may retrieve word variants: ((so sach) or (te sach)) ky nang xa hoi. hieu ve nham ((thuc dong) OR (phuc dong)) thanh do cua te*.
