Perhaps you should try some spelling variations:
thong cong » trong cong, tong cong, thong thong
hien manh » hien hanh, tien manh, hien nhanh
hieu manh » chieu xanh, hieu nganh, dieu hanh
trinh mat » trinh vat, trinh may, trinh sat
trinh mau » trinh cau, trinh may, trinh sau
cong danh » cuong danh, cong dan, cong thanh
danh tuan » anh tuan, manh tuan, danh thanh
tuan cu » tuan tu, quan cua, tuan thu

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 manh) OR (hieu manh)) - hanh ((trinh mat) OR (trinh mau)) thong cong danh tuan cu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien manh) or (hieu manh)) - hanh ((trinh mat) OR (trinh mau)) thong cong danh tuan cu~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien manh) or (hieu manh)) - hanh ((trinh mat) OR (trinh mau)) thong cong danh tuan cu*.
