Perhaps you should try some spelling variations:
chieu sang » chieu sach, chieu xanh, hieu lang
thong cong » trong cong, thong thong, phong chong
hieu manh » chieu xanh, hieu nganh, dieu hanh
hanh manh » hanh mang, lanh manh, hoang manh
tong cong » trong cong, cong cong, dung cong
manh cua » doanh cua, ban cua
dan toan » van toan, dan than, manh toan
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 ((hieu manh) OR (chieu sang)) - hanh manh cua ((thong cong) OR (tong cong)) dan toan cao~.
• Adding a wildcard symbol may retrieve word variants: ho ((hieu manh) or (chieu sang)) - hanh manh cua ((thong cong) or (tong cong)) dan toan cao*.
