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