    【Question】
    How many male users have the log of events at the same longitude of 114? male refers to gender = 'M';

    【Evidence】
    male refers to gender = 'M';

    Please read and understand the database schema carefully, and generate an executable SQL based on the user's question and evidence. 

SQL: SELECT COUNT(T1.device_id) FROM gender_age AS T1 INNER JOIN events_relevant AS T2 ON T1.device_id = T2.device_id WHERE T2.longitude = 114 AND T1.gender = 'M'
