She gathered them and threaded them into beads to sell online.But once she posted them online, someone left a negative review: 'Selling grass seeds? Are you crazy for money?'Days later, this person was pounding the wall in regret: 'I beg you, sell me a grass seed bead, just one! Just one is enough.'Ji You coldly responded: 'Not selling!'And then there's the sparkling stones lying all over the streets that nobody wanted. She picked them up, polished them into bracelets, and sold them online.People lashed out with their words: 'Selling such broken rocks - have you never seen money?'Days later, those same people were crying and wailing: 'I was blind, I was so shortsighted, to overlook such beautiful and pretty stones. I beg you, sell me one.'Ji You spread her hands: 'Gone.'
