Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
luong cong » dung cong, trong cong, cong cong
trung dai » truong dai, truong dao, trung tam
van thang » van thanh, van khang, van hang
ho chieu » theo chieu, hoc thieu, doi chieu
trung da » trung dam, truong da, trung ha
dan than » dan chan, ban than, van than

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 - hanh ((trung da) OR (trung dai)) luong cong ((dan than) OR (van thang)) cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - hanh ((trung da) OR (trung dai)) luong cong ((dan than) or (van thang)) cap~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - hanh ((trung da) OR (trung dai)) luong cong ((dan than) or (van thang)) cap*.
