What does the name Reunion Microfilm 202 1 mean?

The meaning of this name is that this film is telling a story about reunion.

The microfilm called Reunion was directed by Zhang Dapeng and produced jointly by the Propaganda Department of the Central Committee of the Communist Youth League and Zhihu. This is a story about "reunion", a story about "farewell" and a story about a young hero who touched countless people. The shooting technique is very simple, with Grandma Philip Burkart as the protagonist. At first, the family sat around the table to eat. The younger generation seems embarrassed. They bowed their heads and played with each other's mobile phones, which indicated to each other that Philip Burkart had passed away. Later, the village cadres came to visit the families of the martyrs, and the eldest son immediately ran out of the door and shut people out. He secretly sent a blessing message to the old man in the name of Philip Burkart. All the details are very careful. However, grandma learned about the recent situation of her grandson and girlfriend by innuendo and decided to set out to find her girlfriend's home address. At the end of the story, grandma heard the news that her grandson was awarded the first class merit on the train. The last line of defense was finally broken and she couldn't help crying. The pretended calm at the dinner table in front of the younger generation vanished in an instant, and the death of grandson brought great sorrow to his family.

The micro-film Reunion is specially presented to commemorate this patriotic movement. The prototype of the movie character is Xiao Siyuan, a border guard. After the breakthrough, he went back to rescue his comrades-in-arms without hesitation and fought until the last moment, but his young life stayed in the Karakorum Plateau forever. He cast a towering boundary pillar with his own flesh and blood.
