The literal translation of the title of this movie is: Love Spy.
The story is based on the true story of the failed former-USSR attempt on obtaining Chinese results of electro-magnetic resonance researches. The film crew lacked the scientific knowledge and in particular, the comprehensive knowledge of physics and made mistakes of using magnetic resonance instead of electro-magnetic resonance. However, this shortcoming is not a problem for the general audience because none of them have any ideas about this either, what they wanted to see was thrills and suspense, which this movie adequately provided, and thus making it up for the technical flaws.
