Perhaps you should try some spelling variations:
thanh trung » thanh tung
hien hanh » dieu hanh
trung cap » truong cao, trung tam
tuong dan » huong dan, xuong dan, truong dai
hien anh » thien anh, dien anh, tien anh
cap tong » cap nong, cap hoang, gap trong
tung dan » dung dan, huong dan, trung dai
than cap » khan cap, thanh lap, thanh cac

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 anh) OR (hien hanh)) - thanh trung cap tong ((tuong dan) OR (tung dan)) than cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien anh) or (hien hanh)) - thanh trung cap tong ((tuong dan) OR (tung dan)) than cap~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien anh) or (hien hanh)) - thanh trung cap tong ((tuong dan) OR (tung dan)) than cap*.
