Education

UniversityAssociate degree

Nanning Vocational and Technical University, School of Business, Marketing

Sep 2021 - Jun 2024 · 3 yearsNanning, Guangxi, China

Began self-studying Web3 technology in September 2021, experienced the metaverse and NFT boom, and went through a full crypto bull-and-bear cycle. Witnessed the ChatGPT moment in December 2022 and used it to develop smart contracts and web applications. Started exploring Lens-based decentralized social platforms in January 2023 and studied DApp-related technologies.

High School
Sep 2018 - Jun 2021Hechi, Guangxi, China

Learned about Bitcoin in September 2020 and began self-studying political economy and finance. To test my judgment, I put in a few hundred yuan, which had grown 4x by December. In 2021 I took part in the 16x rise of the meme coin SHIB while losing money on other meme coins — and have respected the market ever since.
