Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
tieu xanh » tieu danh, chieu xanh, dieu hanh
quan nang » xuan nang, quan lang, qua nang
luan nang » luan van, van nang, luan san
cong manh » cong danh, duong manh, cong thanh
manh toan » thanh toan, anh tuan, tinh toan
toan cao » toan ban, toan tap

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu xanh - hanh trinh ((quan nang) OR (luan nang)) cong manh toan cao~".
• Adding a wildcard symbol may retrieve word variants: theo tieu xanh - hanh trinh ((quan nang) OR (luan nang)) cong manh toan cao*.
