• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yidan ((wang yang) or (kang han)) ((chen zheng) OR (chen aizheng)) ming zhong zhi ;~".
• Adding a wildcard symbol may retrieve word variants: wang yidan ((wang yang) or (kang han)) ((chen zheng) OR (chen aizheng)) ming zhong zhi ;*.
