Perhaps you should try some spelling variations:
trung tuan » trung thanh, trung tam, tran tuan
nhung cong » dung cong, thong cong, hang cong
trung cua » truong cua, trung cap, dung cua
chao chu » cho chu, cua chu, cao cho
chu xanh » chu manh, chieu xanh, chua xang
cong dan » cong san, cong tan, huong dan
toan cau » toan cao, toan ban, toan tai
toan tap » toan ban

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: chao chu xanh - thanh ((trung cua) OR (trung tuan)) nhung cong dan ((toan cau) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "chao chu xanh - thanh ((trung cua) or (trung tuan)) nhung cong dan ((toan cau) OR (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: chao chu xanh - thanh ((trung cua) or (trung tuan)) nhung cong dan ((toan cau) OR (toan tap))*.
