Perhaps you should try some spelling variations:
chieu sang » chieu sach, chieu xanh, hieu lang
thanh tung » thanh cong
doi chieu » doc hieu, doi chi, ho chieu
cua phan » cua nhan, cua phap, qua phan
tong dan » tuong dan, thong dan, trong dan
dan than » dan chan, ban than, van than
than cap » khan cap, thanh lap, thanh cac
cua han » cua hang, cua nhan, cua ban

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sang - thanh tung ((cua phan) OR (cua han)) tong dan than cap~".
• Adding a wildcard symbol may retrieve word variants: doi chieu sang - thanh tung ((cua phan) OR (cua han)) tong dan than cap*.
