defence planners in beijing and washington view this issue. fairness, i don't think, is a criteria that either country is taking into account. and, linghao, if i can bring you in here, what are the main players saying about these types of controls? in general, the sentiment on the ground is that, you know, this is unfair, because if you're working in china's semiconductor industry, i think, different people in the industry also will have a different view because for chip—makers, they need those us equipment or the japanese equipment to make advanced chips. but, when the equipment ban happened, it also created room for the local equipment makers to step into the market, because previously there's really no market condition for them.
