Yes. Regarding to overseas TC, we have, as I mentioned earlier, we have seen strong demand from overseas markets, especially in the Middle East, South Africa, and ASEAN countries. And so, for those places that, we will rely on our local partner, to obtain the local TC. So, have you already obtained the TC from CAAC? So, when we apply the overseas TC, we can do a streamlined process we call validation of TC, validation of Type Certificate, with the overseas aviation authorities. And this is expected to be a simplified procedure. Consequently, this approach enables us, to expedite market entry and expansion in these countries. And in terms of the order and the production, we're currently receiving a substantial number of orders and pre-orders, which will be fulfilled according to our customers' specific requirements. And typically, that the government and customers commit to pre-orders, or customers, or intentional orders, for example, up to 100 units, and with an initial purchase of five to 10 units for trial operations at local sites. As their operations expand and demand increase, then they will acquire additional products. So, the favorable policies surrounding the low-altitude economy, has provided us an attractive environmental growth. So, consequently, we anticipate a substantial increase in delivery volume throughout 2024. First quarter, we have given our guidance at RMB58 million, slightly increase from quarter-over-quarter, because the first quarter is the Chinese New Year. Typically, there's a long vacation during the quarter. But so far, we look forward that we have seen very strong demand for orders for this year. Currently, our production in Yunfu facility has an annual capacity of 600 units of EBITDA. And we are exploring opportunities to establish other facilities to further support our production capacity as market expand - as market demand grows. Thank you.
