nhu phuong » thu phuong, thi phuong, thu huong
theo lieu » theo tieu, theo chieu, theo yeu
lieu tinh » trieu tinh, diep tinh, bien tinh
bang than » bang thanh, ban than, sang than
than cau » toan cau, phan cau, than cap
luan » quan, lan

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

• Performing a fuzzy search may retrieve terms with similar spellings: theo lieu tinh - hanh ((tran van) or (luan van)) ((nhung phuong) OR (nhu phuong)) bang than cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo lieu tinh - hanh ((tran van) OR (luan van)) ((nhung phuong) OR (nhu phuong)) bang than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo lieu tinh - hanh ((tran van) or (luan van)) ((nhung phuong) OR (nhu phuong)) bang than cau".
• Adding a wildcard symbol may retrieve word variants: theo lieu tinh - hanh ((tran van) or (luan van)) ((nhung phuong) OR (nhu phuong)) bang than cau*.
