It takes a long time to get to Chengdu from what Jumeiyou bought.
It depends on which courier it is. If it's Shentong or Starway, it's usually taken tonight and delivered to you three days later, but if it's Zhongtong, it takes a week, which is completely slow delivery. So you'd better contact Jumei customer service to help you modify the courier company before taking pictures. If it is Zhongtong, it must be changed. To tell you the truth, I am a platinum member.
