Perhaps you should try some spelling variations:
lieu tinh » trieu tinh, diep tinh, bien tinh
chau tinh » cuu tinh, ha tinh, cua tinh
trung hay » trung ha, trung gay, trung huy
trung hai » trung ha, trung dai, trong hai
cong tap » cuong tap, cong tac, cong tan
tap doan » tap quan
doan ban » doanh ban, toan ban, doan van

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 ((lieu tinh) OR (chau tinh)) - thanh ((trung hay) OR (trung hai)) trong cong tap doan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((lieu tinh) or (chau tinh)) - thanh ((trung hay) OR (trung hai)) trong cong tap doan ban~".
• Adding a wildcard symbol may retrieve word variants: ho ((lieu tinh) or (chau tinh)) - thanh ((trung hay) OR (trung hai)) trong cong tap doan ban*.
