Perhaps you should try some spelling variations:
chieu sang » chieu sach, chieu xanh, hieu lang
thanh tung » thanh cong
dung cong » dung trong
cong tinh » cong trinh, cong vinh, long tinh
ho chieu » theo chieu, hoc thieu, doi chieu
toan cao » toan ban, toan tap
va dung » van dung, va duong, vat dung

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

• Performing a fuzzy search may retrieve terms with similar spellings: ho chieu sang - ((thanh trung) or (thanh tung)) va dung cong tinh toan cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sang - ((thanh trung) OR (thanh tung)) va dung cong tinh toan cao*.
