Perhaps you should try some spelling variations:
thuat nhung » thuat hung, thuat chung, thuat chuong
chinh cong » thanh cong, trinh cong
nhung cong » dung cong, thong cong, hang cong
cong thanh » dong thanh, cong trinh, cong tan
thanh toan » thanh hoa, thanh san, tinh toan
ho chieu » theo chieu, hoc thieu, doi chieu
toan cao » toan ban, toan tap

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: ((hoc hien) OR (ho chieu)) sach - ((chinh trong) OR (chinh cong)) thuat nhung cong thanh toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc hien) or (ho chieu)) sach - ((chinh trong) OR (chinh cong)) thuat nhung cong thanh toan cao~".
• Adding a wildcard symbol may retrieve word variants: ((hoc hien) or (ho chieu)) sach - ((chinh trong) OR (chinh cong)) thuat nhung cong thanh toan cao*.
