chieu tinh » lieu tinh, chau tinh, kieu tinh
truong hop » truong hoc, truong hoi, truong lop
thuong dan » thuong han, thuong dam, thuong lan
hop trong » hoc trong, hoa trong, hoi trong
phan cau » phan dau, phan cac, phan tu

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ho ((chieu tinh) or (trieu tinh)) - thanh truong hop trong ((thuong dan) OR (huong dan)) phan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu tinh) OR (trieu tinh)) - thanh truong hop trong ((thuong dan) OR (huong dan)) phan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu tinh) or (trieu tinh)) - thanh truong hop trong ((thuong dan) OR (huong dan)) phan cau".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu tinh) or (trieu tinh)) - thanh truong hop trong ((thuong dan) OR (huong dan)) phan cau*.
