Perhaps you should try some spelling variations:
than change » chain change, can change, mean change
change l.t » change 2.1, change 2.4, change 2.3
l.t sheng » lei sheng
dang hadi » dang hai
ran than » tran thanh, van thanh
yang jie » yang xi, yang yi, yang jun
yang jui » yang judy, yang xi, yang yi
yang jin » yang jun, ying jin, shang jin

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

• Performing a fuzzy search may retrieve terms with similar spellings: ran than change l.t sheng ((((((yang jie) OR (yang jui))) or (yang jin))) or (yang di)) dang hadi ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ran than change l.t sheng ((((((yang jie) OR (yang jui))) OR (yang jin))) OR (yang di)) dang hadi ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ran than change l.t sheng ((((((yang jie) OR (yang jui))) or (yang jin))) or (yang di)) dang hadi ;".
• Adding a wildcard symbol may retrieve word variants: ran than change l.t sheng ((((((yang jie) OR (yang jui))) or (yang jin))) or (yang di)) dang hadi ;*.
