Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, thien anh, thien danh
nhung cong » dung cong, thong cong, hang cong
hieu manh » chieu xanh, hieu nganh, dieu hanh
trang cua » tang cua, trung cua, thang cua
tranh cua » doanh cua, manh cua
cong dan » cong san, cong tan, huong dan
dan chan » dan gian, dan ca, van chat
chan tu » phan tu, han tu, chon tu

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 ((thieu xanh) OR (hieu manh)) - hanh ((trang cua) OR (tranh cua)) nhung cong dan chan tu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu xanh) OR (hieu manh)) - hanh ((trang cua) or (tranh cua)) nhung cong dan chan tu~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu xanh) OR (hieu manh)) - hanh ((trang cua) or (tranh cua)) nhung cong dan chan tu*.
