huong lan » phuong lan, thuong lan, huong dan
hoc phan » hoc pho
tinh cua » trinh cua, sinh cua, tinh chat

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((hoc phan) OR (hoc dan)) tinh - hanh ((trinh quan) or (tinh cua)) dong huong lan than man~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc phan) OR (hoc dan)) tinh - hanh ((trinh quan) OR (tinh cua)) dong huong lan than man.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc phan) OR (hoc dan)) tinh - hanh ((trinh quan) or (tinh cua)) dong huong lan than man".
• Adding a wildcard symbol may retrieve word variants: ((hoc phan) OR (hoc dan)) tinh - hanh ((trinh quan) or (tinh cua)) dong huong lan than man*.
