How does this library implement context

[zhang-qilin]

I'm using gin as the back end of the web, but I can't seem to implement the context when I call, for example when I ask it "What is a chatGPT?" It answered me, but when I asked it again, "Who invented it?" At this time, it replied to me not related to Chatgpt, but other content I hope someone can answer my question, thank you!
