• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang or wing) or lang) yang guang ((zi chen) OR (zhi chen)) zhang xin jeong shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang or wing) or lang) yang guang ((zi chen) OR (zhi chen)) zhang xin jeong shu ;*.
