Perhaps you should try some spelling variations:
ngang thanh » nang thanh, nganh thanh, ngan thanh
theo chieu » theo tieu, ho chieu, theo chu
chieu sach » chinh sach, chiet tach, chieu sang
trung tran » trung tuan, trung thanh, hung tran
cong ngang » cong nhan, cong quang, cong lang
hung cong » nhung cong, hung cuong, phung cong
thanh van » thanh san, thanh toan, thanh phan

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sach - thanh ((trung tran) OR (trung tam)) hung cong ngang thanh van~".
• Adding a wildcard symbol may retrieve word variants: theo chieu sach - thanh ((trung tran) OR (trung tam)) hung cong ngang thanh van*.
