Perhaps you should try some spelling variations:
hanh sinh » hanh tinh, hanh dinh, hinh sinh
bang cong » dang cong, bang song, hang cong
khi xanh » khia canh, thi hanh, thi anh
sinh cua » manh cua, dinh cuu, sinh va
cua bang » chua bang, cua ban, cua dang
cong dan » cong san, cong tan, huong dan
toan tap » toan ban

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 sinh cua bang cong dan ((toan tap) OR (van ban))~.
• Adding a wildcard symbol may retrieve word variants: doi khi xanh - hanh sinh cua bang cong dan ((toan tap) or (van ban))*.
