Perhaps you should try some spelling variations:
thieu tinh » trieu tinh, chieu tinh, thien tinh
truong cua » truong ca, truong quan, truong cao
thong cong » trong cong, tong cong, thong thong
hoc thieu » toc thieu, hoc hien
trung cua » trung tuan, trung cap, dung cua
cong dan » cong san, cong tan, huong dan
than cau » phan cau, than cap, thanh chau
toan cau » 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 thieu tinh - thanh ((trung cua) OR (truong cua)) thong cong dan ((than cau) OR (toan cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu tinh - thanh ((trung cua) or (truong cua)) thong cong dan ((than cau) OR (toan cau))~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu tinh - thanh ((trung cua) or (truong cua)) thong cong dan ((than cau) OR (toan cau))*.
