Perhaps you should try some spelling variations:
thanh trung » thanh tung
chieu xanh » chieu sach, chieu sang, chieu tinh
hien hanh » dieu hanh
trung cap » truong cao, trung tam
cap trong » cay trong, ca trong, cad trong
cong manh » cong danh, duong manh, cong thanh
toan cau » toan ban, toan tap, toan tai
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 hanh) OR (chieu xanh)) - thanh trung cap trong cong manh ((toan cau) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien hanh) or (chieu xanh)) - thanh trung cap trong cong manh ((toan cau) OR (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien hanh) or (chieu xanh)) - thanh trung cap trong cong manh ((toan cau) OR (toan cao))*.
