Perhaps you should try some spelling variations:
ngang thanh » nang thanh, nganh thanh, ngan thanh
chieu xanh » chieu sach, chieu sang, chieu tinh
hoc chieu » hoc thieu, ho chieu, hoc hien
lanh manh » lanh tranh, lan anh, van manh
bang cong » dang cong, bang song, hang cong
hang nong » thang long, han tong
thanh cha » thanh ha, thanh nha, thanh phan
anh manh » anh anh, anh danh, ranh mach

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: hoc chieu xanh - ((anh manh) OR (lanh manh)) cua ((bang cong) OR (hang nong)) ngang thanh cha~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu xanh - ((anh manh) OR (lanh manh)) cua ((bang cong) or (hang nong)) ngang thanh cha~".
• Adding a wildcard symbol may retrieve word variants: hoc chieu xanh - ((anh manh) OR (lanh manh)) cua ((bang cong) or (hang nong)) ngang thanh cha*.
