Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
hanh trinh » canh tranh, hanh chinh
quan trong » gian trong
hoc thieu » toc thieu, hoc hien
qua trong » qua trinh, qua song, qua cong
luong va » dung va
hanh cac » hang cac, hanh cat, nhanh cay
va hanh » van hanh, va thanh, va danh

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 trinh ((qua trong) OR (quan trong)) luong va hanh cac~.
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - hanh trinh ((qua trong) or (quan trong)) luong va hanh cac*.
