Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
hanh manh » hanh mang, lanh manh, hoang manh
dang cong » dung cong
ho chieu » theo chieu, hoc thieu, doi chieu
manh cua » doanh cua, ban cua
cua dang » cua cong, cua ban
cong san » cong tac
than tap » han tap, than cap, thanh lap
phan tap » phan lap, han tap, pha tap
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: ho chieu tinh - hanh manh cua dang cong san ((((than tap) OR (phan tap))) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu tinh - hanh manh cua dang cong san ((((than tap) OR (phan tap))) or (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu tinh - hanh manh cua dang cong san ((((than tap) OR (phan tap))) or (toan tap))*.
