Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
quang tuan » quang thanh, quan luan, quang cua
phong cong » phong chong, thong cong, chong cong
tung tuan » trung tuan, hung tuan, trang tuan
ho chieu » theo chieu, hoc thieu, doi chieu
khan cap » khan ap, than cap, khoan cam

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 - thanh ((tung tuan) OR (quang tuan)) phong cong ty ((phan tu) OR (khan cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu tinh - thanh ((tung tuan) OR (quang tuan)) phong cong ty ((phan tu) or (khan cap))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu tinh - thanh ((tung tuan) OR (quang tuan)) phong cong ty ((phan tu) or (khan cap))*.
