The new regulation was announced by the security branch of the Beijing municipal government and said that residents can file tip-offs through the hotline launched last year, in person, or by post.
北京市政府安全部门宣布了新规，并表示居民可以通过去年发布的热线电话，本人自己或邮寄方式提交举报。

The cash rewards range from 10,000 to 500,000 yuan, depending on how useful the tip-offs are in "preventing or stopping espionage behaviour, or cracking espionage cases", according to several state media outlets including Beijing Daily.
据“北京日报”等国家媒体报道，现金奖励范围在10,000至50万元之间，具体取决于对“防止或制止间谍行为或破坏间谍案”的作用效果。

Authorities said that as the heart of Chinese governance and innovation, Beijing "is the first choice among foreign spy agencies and others who are fiercely carrying out infiltration, subversion, division, destruction and theft".
当局表示，作为中国统治和创新的核心，北京“是外来间谍机构和其他组织渗透，颠覆，分裂，破坏，盗窃的首选”。

Authorities said that in January, a group of fishermen in Jiangsu province found an "unidentifiable object inscribed with foreign words" while trawling for fish, and handed it in to authorities.
当局表示，1月份，江苏一批渔民在钓鱼时，发现了一个“无法辨认的异国字体”，交给当局。

The object was later found to be "a spying device that was collecting data on China".
