Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
chiet tach » chieu sach
thanh tung » thanh cong
thong cong » trong cong, tong cong, thong thong
tam thong » tam thuong, tao thong, nam thong
tung tam » trung tam, vung tam, dung tam
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than cao » toan cao, thai cao, than cap

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 sang))) OR (chiet tach)) - thanh tung tam thong cong dan than cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((((chieu xanh) OR (chieu sang))) or (chiet tach)) - thanh tung tam thong cong dan than cao~".
• Adding a wildcard symbol may retrieve word variants: ho ((((chieu xanh) OR (chieu sang))) or (chiet tach)) - thanh tung tam thong cong dan than cao*.
