Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
thanh toan » thanh hoa, thanh san, tinh toan
phap tinh » phap sinh, phap tieng, phap tang
manh toan » anh tuan, tinh toan
thi phap » theo phap, thi hai, thi ha
mang cua » dung cua, ban cua, cong cua
manh cua » doanh cua, ban cua

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: thi phap tinh - hanh ((mang cua) OR (manh cua)) nhung cong ((manh toan) OR (thanh toan)) cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thi phap tinh - hanh ((mang cua) OR (manh cua)) nhung cong ((manh toan) or (thanh toan)) cao~".
• Adding a wildcard symbol may retrieve word variants: thi phap tinh - hanh ((mang cua) OR (manh cua)) nhung cong ((manh toan) or (thanh toan)) cao*.
