The post did not give details such as when and where the alleged incident happened or which country had sent the spies. It also did not say if any arrests had been made.

The Chinese authorities say they face a heightened security threat from foreign countries, including the United States and its allies, and have called for efforts to catch spies to be redoubled.
The State Security Minister, Chen Yixin, has frequently used social media to promote such calls and appeal to the public for tip-offs.
Earlier this year, Chen said that China must “proactively defend” against foreign spies to strengthen national security and the Communist Party’s leadership.
A new counter-espionage law came into effect in July, which expanded both the definition of spying and the investigative powers of national security law enforcement agencies.
In the post, the ministry also said that stopping spies “not only requires the national security agencies to play a role … but the extensive participation and collective vigilance of the general public”.
