Hong kong drama about solving crimes by psychology.

Although Criminal Investigation IV is a crime-solving drama, it not only involves a lot of criminal psychology, but also shows the ups and downs of the characters' psychology and feelings. Hong Kong drama negotiators also involve a lot of characters' psychology. Mind-reading detectives are the favorite of psychological decoding.

There is a mystery in my mind, which is about psychology and metaphysics. Teng Liming and Chen Jinhong played this piece.
