Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
nhung cong » dung cong, thong cong, hang cong
doi chieu » doc hieu, doi chi, ho chieu
trung dap » trung cap, trung dam, trung lap
trung dai » truong dai, truong dao, trung tam
van thanh » ban thanh
van tuan » van quan, van ban, anh tuan

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: doi chieu xanh - manh ((trung dap) OR (trung dai)) nhung cong ((van thanh) OR (van tuan)) ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu xanh - manh ((trung dap) OR (trung dai)) nhung cong ((van thanh) or (van tuan)) ban~".
• Adding a wildcard symbol may retrieve word variants: doi chieu xanh - manh ((trung dap) OR (trung dai)) nhung cong ((van thanh) or (van tuan)) ban*.
