Perhaps you should try some spelling variations:
hanh trung » thanh trung, hanh trang, manh trung
thieu xanh » chieu xanh, thien anh, thien danh
thong cong » trong cong, tong cong, phong chong
hieu manh » chieu xanh, hieu nganh, dieu hanh
trung cua » truong cua, trung tuan, trung cap
dan chan » dan gian, dan ca, van chat
chan ta » chan tha, nhan tai, nhan tao

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