Perhaps you should try some spelling variations:
khung hoang » phuong hoang
khong hoang » thong hoang, khong hoan, phuong hoang
chieu sang » chieu sach, chieu xanh, hieu lang
hanh trung » thanh trung, hanh trang, danh trung
manh trung » manh tung, thanh trung, manh hung
ho chieu » theo chieu, hoc thieu, doi chieu
anh toan » manh toan, anh tuan, thanh toan
toan cau » toan cao, toan ban, toan tap

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 sang - ((hanh trung) OR (manh trung)) cua ((khong hoang) OR (khung hoang)) anh toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - ((hanh trung) or (manh trung)) cua ((khong hoang) OR (khung hoang)) anh toan cau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sang - ((hanh trung) or (manh trung)) cua ((khong hoang) OR (khung hoang)) anh toan cau*.
