I don’t know Chinese but tried to translate the characters online and this is what I got:
She starts the video talking about her greatest accomplishments. Her first Fashion Month, she was 15 years old and walked 34 shows. She booked many big shows afterwards “the dior, the fendi, blah blah blah” and got a Vogue China and Italia cover.
She then says her goal in the competition was to lose weight (10 pounds).
She says she will quit as not only did she violate the rules, but she wanted to quit. She got really tired during the competition but loves that in the competition, she is with a dozen girls who care about her physical health. She talks about Zhang Tong for a bit, although it’s unclear what her message for Zhang is. (she got eliminated today)
