YOUKU has just announced the new Chinese crime-themed drama Double Track Puzzle (previously titled Black and White Bureau) has exceeded 1 million reservations just 24 hours before it drops.
Yes, the C-drama’s premiere date has also been announced — September 5th, 2025.
The announcement of the drama’s 1 million-plus reservations also came along with a new poster featuring one of the two main leads – Wang Yan Hui – who plays an older railway police officer.
The poster dropped with a message from YOUKU saying:
#TV Series “Double Track Puzzle”# has surpassed 1 million reservations!
Justice may be delayed, but crime will never escape its grasp – once targeted by the veteran anti-pickpocket hero, there’s no chance of getting away!
Streaming exclusively on Youku, join the fight against theft and drugs in Xiatong – don’t miss it. Reserve now.
Double Track Puzzle stars Yang Xu Wen (Strange Tales of Tang Dynasty) and Wang Yan Hui (Regeration), with its plot going like this:
Zhanpeng’s father, a railway policeman, was posthumously named a martyr after he died in the line of duty many years earlier.
Zhanpeng (played by Yang Xu Wen) always hoped to return to the place where his father once worked. However, when he actually comes to Shimotsu and starts working, he finds that the situation here is much more complicated than he thought.
When he first meets Tu Hongjiang (Wang Yan Hui), an older railway police officer, he believes the older police man is behaving very suspiciously while handling a drug trafficking case, which puts Zhanpeng on guard against him.
Will Zhangpeng’s suspicions be born out, or will he learn something else is going on instead?
Look out for the Chinese drama dropping on YOUKU tomorrow.
