Perhaps you should try some spelling variations:
wang hong » wang yong, wang hyoung, wang lihong
shang hai » shang kai, dang hai, chang ha
der rent » der re
der rede » der redner, der re
oil rent » oil rents, oil trend, oil real
liang li » ling li, qiang li, liang wei
wong yue » wang yue, hong yu

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang hong kong ((((der rent) OR (der rede))) or (oil rent)) liang li ((shang hai) or (wong yue)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang hong kong ((((der rent) OR (der rede))) OR (oil rent)) liang li ((shang hai) OR (wong yue)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang hong kong ((((der rent) OR (der rede))) or (oil rent)) liang li ((shang hai) or (wong yue)) ;".
• Adding a wildcard symbol may retrieve word variants: wang hong kong ((((der rent) OR (der rede))) or (oil rent)) liang li ((shang hai) or (wong yue)) ;*.
