Perhaps you should try some spelling variations:
trong khoa » truong khoa, tuong khoa, trung khoa
tang duong » tang cuong, tang dong, tuong duong
mot chieu » doi chieu, ho chieu
trung kho » trung khoa, truong khoa, trung hoc
duong van » duong va, luong va, dang van
van toan » van tuan, van tan, van thanh
toan tap » toan ban
doi chi » doi khi

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: ((mot chieu) OR (doi chi)) xanh - thanh ((trung kho) OR (trong khoa)) tang duong van toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((mot chieu) or (doi chi)) xanh - thanh ((trung kho) OR (trong khoa)) tang duong van toan tap~".
• Adding a wildcard symbol may retrieve word variants: ((mot chieu) or (doi chi)) xanh - thanh ((trung kho) OR (trong khoa)) tang duong van toan tap*.
