Yes. It's our goal actually to continue to generate leverage in the expense line items, right. So certainly, first marketing needs to go down as a percentage of total revenue. I think for this JG Alliance business, we think the leverage is pretty high. We will continue to go up, okay. And what we need to do is actually work on is actually to get the leverage for the subscription business. Subscription business, actually per head revenue, is still not in the ideal range yet, okay. So that's why going forward, we are actually going to have actually already building sort of the KA customer and like a sales team, which does not exist before. And this KA customer, they will serve the industry basically verticals, vertical by vertical and serve companies like China Merchants Securities, right. Such kind of a customer. They can generates RMB4 million revenue also, right. So this is where the sales efficiency will come from, right, by serving the large customers, right. And so this is ongoing process. And not only on the sales and marketing, also our R&D, we will continue to drive the efficiency, okay. We will continue to optimize our resource utilization rate. We will continue to allocate the human resource into new product innovation, okay. And also, we will cut back the resource originally devoted into the older products, right, legacy product, push products, right. So that's sort of ongoing process we are currently implementing. So I think that going forward, yes, we should continue to see our operating leverage.
