    Hi Liu Yang,

    I  have forward your inquiry to quality engineers via internal email. I am trying to reduce the interpretation of our date marking information in the public forum. You should hear from us shortly. 

    I am going to close this inquiry for now. If you have further questions, please let us know. 

    Best,

    Raymond
