trung cap » truong cao, trung tam
dung cong » dung trong

• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu tinh - thanh trung cap ((han cong) or (((dang cong) OR (dung cong)))) sac thai cao~".
• Adding a wildcard symbol may retrieve word variants: ho chieu tinh - thanh trung cap ((han cong) or (((dang cong) OR (dung cong)))) sac thai cao*.
