How to find boyfriend in real life?

I walked to achieve 10k steps and reached the market in a wealthy neighborhood. I was browsing what to buy when a Chinese guy (we’re not in China) approached me and started a conversation. He asked about cereals, and I explained. Then I left. I am lonely asf, and it was the first time someone approached me to talk. Do you think I should have talked to him more and gotten his number? Or should I go to that market again and try to talk to someone new?
