Among all the solution of the 'zh-cn' methods, which path is most often used?
solution refers to SolutionId; zh-cn refers to Lang = 'zh-cn'; path that is most often used refers to MAX(COUNT(Path));
SELECT T1.Path FROM Solution AS T1 INNER JOIN Method AS T2 ON T1.Id = T2.SolutionId WHERE T2.Lang = 'zh-cn' GROUP BY T1.Path ORDER BY COUNT(T1.Path) DESC LIMIT 1
