In the past few years, Andy Lau's film the orphan has impressed audiences. It is not a tear-jerker, but it is a wake-up call to love. 

      In the lost and lonely, Andy Lau plays the real Sun Haiyang. The ending of the film does not have a happy ending, but in reality, sun Haiyang is lucky to find his lost son Sun Zhuo. And Sun Haiyang can find his son, is the strong support of people from all walks of life, but also can not do without advanced facial recognition system.

In addition to the above-mentioned Sun Haiyang case, recently, based on face recognition, nanchang resident Wang Shaohui (not his real name) and his wife finally met their son Wang Qiang (not his real name) , who had been missing for 32 years.

Soon after, facial recognition identified Wang shaohui, a resident of Nanchang Qingyunpu District's Hondo Yayuan Plaza, who has a 60% facial similarity to Wang Qiang and may be related to him, the relationship was then confirmed by DNA comparison.
