Perhaps you should try some spelling variations:
cheng wei » chen wei, cheng hei, cheng siwei
wei chen » wei shen, frei chen, jui chen
yang jie » yang jin, yang di, yang yi
yang jui » yang judy, yang di, yang yi
tin tan » tan tan, wing tan
yang xi » yang di, yang yi
hai » hadi, haji, hari

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((tin can) OR (tin tan)) cheng wei chen ((((yang jie) or (yang jui))) or (yang xi)) dang hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tin can) OR (tin tan)) cheng wei chen ((((yang jie) OR (yang jui))) OR (yang xi)) dang hai ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tin can) OR (tin tan)) cheng wei chen ((((yang jie) or (yang jui))) or (yang xi)) dang hai ;".
• Adding a wildcard symbol may retrieve word variants: ((tin can) OR (tin tan)) cheng wei chen ((((yang jie) or (yang jui))) or (yang xi)) dang hai ;*.
