Perhaps you should try some spelling variations:
thanh trung » thanh tung
chieu xanh » chieu sach, chieu sang, hieu manh
chieu tinh » trieu tinh, lieu tinh, chau tinh
trung cua » truong cua, trung tuan, trung cap
tong cong » trong cong, cong cong, dang cong
dung cong » dung trong
gian soan » gian dan, giai doan, bien soan
tan gian » tran gian, dan gian, van gian

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 xanh) OR (chieu tinh)) - thanh trung cua ((tong cong) OR (dung cong)) tan gian soan~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu tinh)) - thanh trung cua ((tong cong) OR (dung cong)) tan gian soan~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu tinh)) - thanh trung cua ((tong cong) OR (dung cong)) tan gian soan*.
