Do you understand what is involved with the manufacture of a modern integrated circuit? You are talking about one of the most complex manufacturing processes on earth. Yifu is clearly at fault for missing the deadlines he promised - but that does not change the fact that getting these chips manufactured is far more complex than sending TSMC a request for some more chips.
Yes I understand what is involved ... look at the last few orders he did, remember what he did, do it again so it arrives at the time he promised ... oh wait, I forgot to add, sell the chips to someone else and then run another order that will of course be late ...
