Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
trung cong » truong cong, trong cong, trung uong
hoc thieu » toc thieu, hoc hien
hanh manh » hanh mang, hoang manh, thanh minh
lanh manh » lanh tranh, lan anh, van manh
cua trung » cua truong, xuan trung, cua nhung
manh toan » thanh toan, anh tuan, tinh toan
dan than » dan chan, ban than, van than

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 thieu xanh - ((hanh manh) OR (lanh manh)) cua trung cong ((manh toan) OR (dan than)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - ((hanh manh) OR (lanh manh)) cua trung cong ((manh toan) or (dan than)) cau~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - ((hanh manh) OR (lanh manh)) cua trung cong ((manh toan) or (dan than)) cau*.
