Perhaps you should try some spelling variations:
chieu xanh » chieu tinh, hieu manh
chieu sang » hieu lang, nhieu tang
chieu sach » chinh sach, chiet tach, hieu cach
nhung cong » dung cong, thong cong, hang cong
chinh va » chinh ta, chinh tai, hanh va
cong tam » cong tac, cong tan, cong nam
tam than » ban than
than ma » than man, than va, khan ma

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 (chieu sach)) - hanh chinh va nhung cong tam than ma~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((((chieu xanh) OR (chieu sang))) or (chieu sach)) - hanh chinh va nhung cong tam than ma~".
• Adding a wildcard symbol may retrieve word variants: ho ((((chieu xanh) OR (chieu sang))) or (chieu sach)) - hanh chinh va nhung cong tam than ma*.
