Hello, I'm Sister Hua, Baidu Customer Service. I'm glad to serve you. I'm asking for you. It takes some time to inquire, type and tidy up, which has kept you waiting. I will try my best to find the relevant content for you. If the follow-up service can satisfy you, please give me five-star praise. If the service is not in place, please give me pertinent advice, too. Thank you.
