Let's talk about the evaluation of the four parts of Ji Xiaolan with iron teeth and copper teeth

The fourth part has been greatly improved in shooting techniques and actors' acting skills, which is perfect, but the plot is somewhat unsatisfactory, especially the parts of Songgege and Qinghuashan, which are somewhat boring. I prefer 23 movies to 23 movies. To tell you the truth, I'm a little disappointed with the fourth one, but I'm still looking forward to the fifth one.
