Thank you, Alvin. The dividend policy, I think that it's a right balance between -- we need to evaluate and consider whether we have some future M&A with what's due, whether we need to invest over there. And to -- and we need to consider what's the right level of return for investments for shareholders. So we balance these 2 factors and decide whether we need to pay the dividends.
I think in the filter, we will also consider these 2 factors, and decide to pay dividend or not. But by the end of the day, I cannot give you more update about that. So every year, we will evaluate these 2 factors and draft for the right balance and make decision. So we will let the class know when we want to do it again. But generally speaking, when we have more cash coming in and we have wirestream cash flow and if we don't have any future M&A we want to do in the short-term, so we will consider that.
And the second question about the double-teacher model, increase on details about this call or not, something like that. I think, again, the double-teacher model is good. We are the first company in K-12 area to provide this model and we're inventing a lot of new features in this model. And -- but again, this model is still in the early stage. It work, but it still need more time to tweak on the details to make sure every detail is right. So we don't have any trend to hurry on, to accelerate the coverage of double-teacher classrooms in China. There are still ways we could well pace, control it to be and try something different, to our -- tweak our details to make it right. So we give the thing and this model more patience about that.
Now specifically about price, based on what we see today, we don't give any discount on this. And again, I don't think discount is -- I'll make it price promotion or maybe something like that. The most important factors when we talk about the effectiveness of the double-teacher models, what we need to care more actually is the learning experience, learning management system, and how we can react and how these teachers, assistants, students can interact in the classroom, before the classroom, after the classrooms. So what we care more is the quality, not their price. So that's what we can see today. We still manage the double-teacher centers in very [indiscernible] , and so far, we don't have any intention to hurry up in this area.
