  def stock_info(
      symbol: str = field_symbol,
      market: str = field_market,
  ):
      markets = [
          ["sh", ak.stock_individual_info_em],
          ["sz", ak.stock_individual_info_em],
          ["hk", ak.stock_hk_security_profile_em],
      ]
      for m in markets:
          if m[0] != market:
              continue
          all = ak_cache(m[1], symbol=symbol, ttl=43200)
          if all is None or all.empty:
              continue
          return all.to_string()
  
      info = ak_search(symbol, market)
      if info is not None:
          return info.to_string()
      return f"Not Found for {symbol}.{market}"
