  def stock_news(
      symbol: str = Field(description="股票代码/加密货币符号"),
      limit: int = Field(15, description="返回数量(int)", strict=False),
  ):
      news = list(dict.fromkeys([
          v["新闻内容"]
          for v in ak_cache(stock_news_em, symbol=symbol, ttl=3600).to_dict(orient="records")
          if isinstance(v, dict)
      ]))
      if news:
          return "\n".join(news[0:limit])
      return f"Not Found for {symbol}"
