Place to leave a luggage in Lijiang or Qiaotou

I've got a question about the place in LJ or Qiaotou, where we could leave our main luggage safely (and reasonably charged). We're planning to reach Lijang in the afternoon from Dali, leave there the main load, and set off to the Tiger Leaping Gorge with a convenient weight on our backs. Is there somewhere a convenient place for that purpose?
