Rich girl classmate, 5 apartments in Shenzhen, savings of ten million, net worth over a hundred million. Coming to Beijing for business, stopping by to see me, asking about stock trading, and asking me to tell her what to invest in.

I've talked through all the sectors from the trade war to the pandemic, from new energy to big consumption, from the metaverse to VR, from pre-made dishes to the digital economy.
My classmate sighed: You poor people, you don't have many dollars, but you really do know a lot.
