If I understood it right (my Chinese not very good so might be not entirely correct) , she was talking about her experience with tailoring, patterns and she didn't like that you have like the S, M, L measurements for clothes and I think she made her own patterns? And six years after starting her journey she really enjoys her life, going to different scenic locations wearing her hanfus/clothea she made.
she also began by talking about how she thought sewing was difficult and how discovering these paper patterns in university made her realize that it was doable. I think it sounds like she's trying to encourage others to take up sewing, by telling them about the simpler methods she's discovered? and also how she likes doing this as her livelihood. My chinese is also not super great so i could be missing things too, and translating is hard 😅
