In the late 90's, in China, Tu Xiaoyi, an high school student, takes no interest in marks and prefers to play video games with his friend nicknamed "Peanut." One day, he was chosen by his teacher to become the class representative with Yao Zhetian, a very cute girl. He will experience his first love and disappointments.


Manhua artist Pocket Chocolate began production of a full-length animation film adaptation of his work Zuori Qing Kong (published outside China as Crystal Sky of Yesterday) in July 2015, after seeking feedback on a sample pilot adaptation. The film's target audience is viewers born in the 1980s and 1990s. In order to prepare for production, the animation team spent time studying the Lanxi cityscape, including finding textbooks, school desks, and bicycles used in the film's time period.

It was a shame the subs I used didn't fully represent the story.

The movie has some incredible animation and breathtaking backgrounds, but is wildly inconsistent. Not that any of it is terrible, but some parts clearly stood out as rushed or with janky cgi character movements. Other scenes are quite striking, with fluid animation that adeptly conveys both action, and more subtle body language. In fact, one of the film’s greatest strengths is the animation’s ability to capture the personality of the characters in each scene, whether it’s the rebelliousness abandonment of Qi Jingxuan, or Yao Zhe Tian’s quiet desperation to find purpose and break free from her overly structured life. Even side characters like the teacher, ...

Mixed Feelings
Chinese animation can be strange, or maybe the right word is unnatural, in intervals. Regardless of the specific interpretations, their attention to movement is rough, so much so that otherwise passable production qualities pale in comparison. It's not a matter of resembling realism, but the frame-by-frame continuity needs a purpose, something that's missing in Zuori Qing Kong. The motion of a character's upper body alongside their expressions is imperative in relaxed atmospheres, and hyperactive blinking on lifeless faces doesn't quite sell the scenario. Despite these jarring displays, the film has an aesthetic, a sense of visual direction hoisting up the weaker components. It's usually confined ...
