If you want to say that the most "bad" plot of the TV series "South to North" should be the early stage, the reason is very simple, because the previous plots are all small cases, which are not exciting at all, not exciting enough and not exciting enough, such as Wang Xun's Wang Guofu lost his bag, and for example, Tang Guoxing played by Bao Bell cut his wrists and committed suicide, which can be said to be mediocre, and it is a pity that these actors appeared so briefly. 
But with the development of the plot, I found out that in fact, many cases in this drama are paving, for example, the old blind man played by Ni Dahong before, he has been waiting in the car for more than ten or twenty years, just waiting for his abducted daughter, or catching the trafficker who abducted his daughter, and this case has not been solved so far, which is very embarrassing, of course, it should be solved in the end, because the trafficker is too arrogant and has been committing crimes. 
Of course, to say that the most troublesome and dangerous case is actually a drug trafficking case, before Ma Kui pulled Wang Xin, who was transferred to Hongyang Station, to carry out the mission together, the two were originally dressed in disguise, no one knew that Wang Xin was recognized by the king of thieves at first sight, Wang Xin caught a pickpocket, and he had a white-faced and white-bearded thief by his side, he didn't know, but he was recognized by the king of thieves. 
As for Ma Kui, he was recognized by Peng Mingjie at first sight, and Peng Mingjie looked at him left and right, knocking on the side, as if he was testing Ma Kui, and later Peng Mingjie *** came to see that he would probably have an incident later, and it might even have something to do with the drug dealer case. Later, when Wang Xin and Ma Kui arrested the drug dealer together, Wang Xin shot and killed the drug dealer, which finally led to the interruption of the clues of the case, so it became more difficult for Wang Xin and Ma Kui to solve the case. 
However, in the new plot, Wang Xin and Ma Kui caught a drug addict on the train, Ma Kui proceeded from reasonableness, and let the drug addict take the initiative to confess a drug dealer, Wang Xin and Ma Kui teamed up to catch the drug dealer, and the drug dealer confessed his upline, Wang Xin and Ma Kui rushed to Shenzhen to find the three-headed strong, but what they wanted was to catch the thief and catch the dirty, and wanted to catch the three-headed strong and completely take down the drug dealers in one fell swoop. 
It's just that what Wang Xin and Ma Kui didn't expect was that they saw a man dressed as a student, pretending to be a student, and connecting with Santou Qiang, Wang Xin saw that Santou Qiang and this man dressed as ** were using cigarette butts to transmit information, so they arrested this person, but what they didn't expect was that this man dressed as ** was none other than Hou Sanjin, who had stolen Tang Guoxing's watch on the train before.
When Hou Sanjin was arrested, it can be said that he was miserable, crying a lot, all kinds of methods have been used, just to avoid going to jail, in the end, although he changed his ways, specializing in selling watches on the train, it can be regarded as a good mix, in the later plot Ma Kui and Wang Xin saw Hou Sanjin several times in the car, he is still a thief, but what people didn't expect is that this person actually became a drug dealer.
Hou Sanjin was arrested this time, and he deserved it, he committed a series of crimes, and he was related to drug dealers, so it was appropriate to go in for a few years this time. And with Hou Sanjin being arrested, it will not be difficult to solve this drug trafficking case, after all, Hou Sanjin is also an "old acquaintance" of Wang Xin and Ma Kui, and there is a high probability that he will confess his upline after being arrested.
This Hou Sanjin is actually a character who appeared very early, he appeared when Tang Xingguo's watch played by Bao Bell was stolen, what he didn't expect was that the foreshadowing was so far-reaching, in the later stage, this person still has such a heavy role, Hou Sanjin who doesn't look like a good person still has a lot of scenes, and his arrest is related to the most difficult case in this drama, which is indeed surprising.
can only say that the foreshadowing of this drama is really far-reaching, in addition to Hou Sanjin, there are also cases such as the old blind man and the child abduction and trafficking, and he is likely to catch the traffickers in person later. In addition, there are such as Peng Mingjie and Jia Jinlong, one of these two is even likely to have something to do with the corpse shredding case, the ** of the corpse shredding case has been provoking**, Ma Kui swore not to be a police officer if he didn't solve the case, this ** is very deep, and it is likely that there has been a foreshadowing for a long time.
All in all, the follow-up plot of this drama is becoming more and more exciting and exciting, because a lot of foreshadowing has been laid in the early stage, which makes people look forward to the follow-up plot, hoping to be more exciting.
