Perhaps you should try some spelling variations:
truong cua » truong ca, truong quan, truong cao
nhung cong » dung cong, thong cong, hang cong
hien xanh » hien hanh, hien nhanh, chieu xanh
trung cua » trung tuan, trung cap, dung cua
van than » van thanh, van thang, van tuan
dan chan » dan gian, dan ca, van chat

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: hoc hien xanh - thanh ((trung cua) OR (truong cua)) nhung cong ((van than) OR (dan chan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien xanh - thanh ((trung cua) OR (truong cua)) nhung cong ((van than) or (dan chan)) cau~".
• Adding a wildcard symbol may retrieve word variants: hoc hien xanh - thanh ((trung cua) OR (truong cua)) nhung cong ((van than) or (dan chan)) cau*.
