Perhaps you should try some spelling variations:
ngang chuan » zhang chuan
chinh luat » chinh luan, hinh luat, trinh luat
hieu manh » chieu xanh, hieu nganh, dieu hanh
cong cong » cong dong, trong cong, dang cong
dung cong » dung trong
hoc hieu » hoc thieu, hoc hien, doc hieu
chuan ha » chuan he, quan ha, chuan bi

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hieu manh - hanh chinh luat ((cong cong) OR (dung cong)) ngang chuan ha~".
• Adding a wildcard symbol may retrieve word variants: hoc hieu manh - hanh chinh luat ((cong cong) OR (dung cong)) ngang chuan ha*.
