Perhaps you should try some spelling variations:
wang xiliang » wang liang, kang miliann, wang liming
deng ziliang » zeng ziqiang, peng liang
zheng lei » zhang lei, zheng lili, zhen wei
zheng li » zheng liu, heng li, zhang li
zhang i » zhang ii, zhang li, zhang si
i cohen » m cohen, _ cohen, j cohen

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

• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang xiliang) OR (deng ziliang)) zhang i cohen ((zheng li) OR (zheng lei)) cong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang xiliang) or (deng ziliang)) zhang i cohen ((zheng li) OR (zheng lei)) cong shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang xiliang) or (deng ziliang)) zhang i cohen ((zheng li) OR (zheng lei)) cong shu ;*.
