Perhaps you should try some spelling variations:
nhanh muong » nhanh chuong, nhanh quang, nhanh chong
thanh tung » thanh cong
thanh long » thanh cong, thang long, thanh huong
theo chu » theo chieu, cho chu, chao chu
chu sach » cau sach, thu sach, chieu sach
cong tan » cong tac, cong san, cong thanh
toan ban » van ban

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: theo chu sach - nhanh muong ((thanh tung) OR (thanh long)) cong tan ((toan tap) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu sach - nhanh muong ((thanh tung) or (thanh long)) cong tan ((toan tap) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: theo chu sach - nhanh muong ((thanh tung) or (thanh long)) cong tan ((toan tap) OR (toan ban))*.
