I would like to confirm with you:
I received an email dated 20th Jan from DO. She requested us to keep stock of 10k for MA and 15k for MB. So the quantities we produced for MA: 530 (already shipped); for MB: 640 (100 of them already shipped, stock 540). Please refer to the attached file.
Since we have received files [or drawings] for new version MA and MB, we would like you to confirm if we need to stop the stocking instruction from DO, but wait for your new stocking instruction [他的新指令有了吗?]
In addition, shall we keep the new version MB after we use up the existing MB version? That is, a running change?
