Perhaps you should try some spelling variations:
thanh trung » thanh tung
chieu sang » chieu sach, chieu xanh, hieu lang
chiet tach » chieu sach
trong manh » trong minh, trong anh, trong mach
manh toan » thanh toan, anh tuan, tinh toan
trung ap » trung cap, trung lap, trung tam
toan tap » toan ban
ap dung » xay dung, van dung

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: ho ((chieu sang) OR (chiet tach)) - thanh trung ap dung trong manh toan tap~.
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sang) or (chiet tach)) - thanh trung ap dung trong manh toan tap*.
