Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
hanh mang » nhanh mang, hanh trang, nhanh lang
cua nhung » va nhung
manh toan » thanh toan, anh tuan, tinh toan
chi danh » chi dan, chi dinh, chi hanh
mang cua » manh cua, dung cua, ban cua
chi anh » chi hanh, thi anh, chi nhanh

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 ((chi danh) OR (chi anh)) - hanh mang cua nhung cong ((xuan toan) OR (manh toan)) cao~.
• Adding a wildcard symbol may retrieve word variants: doi ((chi danh) or (chi anh)) - hanh mang cua nhung cong ((xuan toan) or (manh toan)) cao*.
