Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
trung cua » truong cua, trung tuan, dung cua
trung cap » truong cao, trung tam
hang cong » dang cong, hang nong, bang cong
cong doan » cong dan, cong hoan, dong doanh
ho chieu » theo chieu, hoc thieu, doi chieu
phan cac » nhan cach, phan dau, phan lap

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: ho chieu tinh - hanh ((trung cua) OR (trung cap)) hang cong doan ((phan tu) OR (phan cac))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu tinh - hanh ((trung cua) OR (trung cap)) hang cong doan ((phan tu) or (phan cac))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu tinh - hanh ((trung cua) OR (trung cap)) hang cong doan ((phan tu) or (phan cac))*.
