Okay, thanks for the questions. To address the first one, we believe there is a great credential for growth. Firstly, on the addressable market, the number of devices transacted on our platform this year reached a record high of over RMB30 million. However, this is still a small portion compared with 590 million new electronic devices sold in China annually according to CIC. In addition, other devices, including phones, tablets and laptops, et cetera, totaled RMB2.7 billion, indicating a low rate of recycling. Secondly, on our penetration rate at city level, our services have relatively little presence locally. It was low single-digits in 70% of the cities in China, as we mentioned on the last earnings call. We are poised to increase that through steadfast implementation of our city level service integration strategy. To answer your question to business priority, we plan to seek an accelerated growth of 1P business with steady profit and a healthy growth of 3P GMV with more attention to the efficiency and profitability of the marketplaces. Looking back at 2021, GMV of 1P business increased by 69.6% year-over-year, outlining the growth rates over the past years. We attribute this to the solid progresses in new store openings, a stronger trading partnership with JD and expanding 1P direct to retail business on Paipai. The stores continue generating profit, in the fourth quarter 2021, net margin of mature stores reached 4.0%, improving our confidence in serving more customers and top up our efforts in these stores. We expect to open 200 new standard AHS stores in 2022. Furthermore, we aim to add 500 partner stores, i.e., store-in-store, a new format in collaboration with local partners as a part of the city level service integration strategy. This is to facilitate trading and to expand consumer reach through the synergy with JD and mobile brands and it helps to grow our footprint in local retail scenarios. We take city level service integration model, the key to the next stage of growth for PJT and Paipai marketplace. This will be achieved through sourcing premium goods more efficiently. In the first quarter of 2022, we have launched a service integration model in 22 pilot cities to highlight the growth rate of B2B business in 12 pilot cities exceeded 100%, including Shenyang, Nanchang and Hefei provincial capital. By leveraging the city level service integration model, we dive deep into this B2B business. We digitalized the transactions and encourage online transactions. Not only do we serve dealers but also new device retailers, thus forming a closed loop from recycling from users when buying a new device through inspection at our facilities and directly to the retail end.
