Perhaps you should try some spelling variations:
hanh truong » hanh trong, anh truong, manh truong
dinh trong » sinh trong, chinh trong, dinh thuong
khi xanh » khia canh, thi hanh, thi anh
ca nhung » cua nhung, cam nhung, ca nung
cong dan » cong san, cong tan, huong dan
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: doi khi xanh - ((hanh truong) OR (dinh trong)) ((ca nhung) OR (va nhung)) cong dan toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi khi xanh - ((hanh truong) or (dinh trong)) ((ca nhung) OR (va nhung)) cong dan toan cao~".
• Adding a wildcard symbol may retrieve word variants: doi khi xanh - ((hanh truong) or (dinh trong)) ((ca nhung) OR (va nhung)) cong dan toan cao*.
