What character does Fan Wei play in the movie "There's no end to it"?

I think the April Fool's Day-born Lao Fan (played by Fan Wei) is a typical grassroots straight man, divorced for many years, he did a mundane courier job, with a secondary character of the son of the second Fan (played by Liu Junhao), the two men live a happy life, but can not help but be shy.

This year, Lao Fan's birthday was very sad, lost the customer's parcel by the boss (Fan Placid) claims, by the lottery store owner (Kong Lianshun) ridicule, offended the square dance brother (Mike Sui) was spoofed, late delivery of the odd customer (Xue Zhiqian) love letters led to people jumping off the building, in front of his son's homeroom teacher (Jennifer Jia) bragged about the laughing stock, the son of the classroom teacher (Jennifer Jia). Witness the small ruffian (Song Yang played) bully, want to fight but backed out of the battle to fall into a two-sided bad reviews.

What he didn't expect was that God had deliberately played a huge joke on him: his life was accidentally caught in a "dead cycle", stuck in the same day and unable to get out. In the day to day time predicament, Lao Fan from emotional frustration to breakthrough, in the guidance of the man (Lin Renewal), opened the "fancy self-help" mode, experience life's many forms, step by step to evolve into an impressive "one-day winner! "The first time I've ever seen a woman in the world, I've seen a woman in the world. He gave the lottery ticket to the old man, because he thought he would always be in the No. 1 jump can not go out, holding the lottery ticket is meaningless! In the end.

Finds himself out to #2, but the ticket is taken by the old man and cashed in! The movie tells the story of Lao Fan, who was born on April Fool's Day, and who encounters a series of strange characters and experiences a series of tragic events on his birthday, after which his life is plunged into a "death cycle". In a day-to-day time predicament, a thousand different kinds of fancy life attracts people to laugh and cry?
