Tim : I think the partnership is absolutely essential to promoting Alibaba culture. It is the ultimate keeper of our culture, our values. What we talk about most of the time is all about a culture values organization. It's not focused on business issues. And that's one of the things that has kept me going at Alibaba all these years is that we're a company that is driven by mission that by and large adheres to our values. And that the role of the partnership is as, as leaders ensuring that continues to be the case. That despite all of the business pressures, despite all of the international pressures and domestic pressures, that we stick to our mission, vision and values.
