Perhaps you should try some spelling variations:
trinh quang » tranh quang, trinh dung, trinh luan
chieu sang » chieu sach, chieu xanh, hieu lang
trinh quan » trinh luat, trinh han
dang huong » dang thuong, dang hung, dong huong
doi chieu » doc hieu, doi chi, ho chieu
dan than » dan chan, ban than, van than
than cau » toan cau, phan cau, than cap

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

• Performing a fuzzy search may retrieve terms with similar spellings: doi chieu sang - hanh ((((trinh quang) OR (tinh quang))) or (trinh quan)) dang huong dan than cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu sang - hanh ((((trinh quang) OR (tinh quang))) OR (trinh quan)) dang huong dan than cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sang - hanh ((((trinh quang) OR (tinh quang))) or (trinh quan)) dang huong dan than cau*".
