Is there any improved schedule? Please try to start it / the mass production on 18 Sept per our requested before.

We booked the inspection for today afternoon, however, your QC was arrived to the factory this morning, and there is not 100% good available in this morning. Would you please advise your QC still until to the afternoon to perform the inspection?
