Thank you, Lai Song. Now, please let me translate first. Hello, everyone, and thank you for joining us today. The year of 2020 represented another milestone in ZTO's development. We maintained our lead in overall customer satisfaction and grew annual parcel volume by 40.3% over last year to exceed RMB17 billion, expanding our number one market share to 20.4%. 2020 was also an extraordinary year. We remained true to our Shared-Success philosophy, leveraging on our extensive coverage and brand recognition, leading scale and capacity, continuously improving operational efficiency, and trusted in the collaborative network partners. We maintained top rent [ph] to service quality, while growing volume rapidly. Amid the hard blow of pandemic, frequent changes in industry dynamics and a fierce price competition. We recorded RMB4.59 billion of adjusted net profit, demonstrating a highly differentiated quality of earnings compared to our worker’s markets here. ZTO's consistent strategy to accelerate parcel volume acquisition and expand market share while balancing service quality and profitability has been proven effective. First, we focused on building transit capabilities. On one hand, we acquired relatively large tracts of land for constructing comprehensive smart logistic parks with integrated operations such as in-warehouse processing logistic fulfillment. While enhancing the level of automation and the utilization, we are designing sets that are useful for coordinated, yet varied operational flows. We have increased the proportion of self-owned fleet, including high capacity trailer trucks and improved the engine-to-trailer ratio. We also better organized the use of third-party logistics to supplement our own fleet. On the other hand, we continue to enhance the development of IT technology platforms. In addition to the dramatic of upgrades of our existing operating modules such as Zhangzhongtong, Shenzhou, Galaxy and [BBP]. We achieved the new breakthroughs in areas such as user interface, process streamlining, new product innovation and ecosystem value proposition. With consistent capacity development, refined process management, economies of scale and favorable ETC policies during the pandemic, the combined sorting and transportation cost per parcel decreased to 14.3% year-over-year. Secondly, we continue to expand development on pickup and delivery and strengthened our last-mile capacity and service quality. While focusing on scale and the efficiency of transit and sorting centers, on one hand, by providing financing, technology support and operational knowhow, we helped our network partners who reached the capacity bottleneck or faced the challenges in managerial capabilities. Given the strength of the Group, we are able to modify subsidy policies frequently and appropriately to help, coping with highly competitive and consistently changing market conditions. On the other hand, for those risk segments and the negative growth or weak quality performances, we deployed a grade-based attention approach, which then quartermaster [ph] to locally adjust problems and implement improvement plans. Thirdly, we accelerated last-mile developments. Since its beginning in 2018, ZTO's last mile presence has been increasingly enhanced. By the end of 2020, we have more than 68,000 last mile posts, leading the industry. Last mile delivery methods other than door-to-door, such as the last mile posts have not only effectively reduced the handling load and profit pressure, but also provided movement for front-end customer acquisition. Meanwhile, the proactive trial and adaptation of the Express plus model provided valuable experience in supply chain approach based on IoT mindset, thereby strengthening connectiveness with our last mile consumers. As the commencement year of the 15th five-year plan, 2021 will also be an important year for ZTO to build brand value and recognition, expand and upgrade its services and its products, and establish collaborative ecosystem. While, carrying forward our recurrent initiative, we will focus on the following aspects. First, to ensure sustainable growth, we shall take on corporate social responsibilities, including operating in an environmental-friendly way and helping farmers and alleviating poverty. Our efforts are underway, such as new green packaging, upgraded vehicles that run on renewable energy, wind services to villages and the rural workshops, offer logistic solutions to help revitalizing rural economy and provide basic care for grass-root walkers. Secondly, we are optimistic on the growth prospects of the express delivery industry in China. Our top priorities are to solidify our leading position in parcel volume and further expand our market share. We will increase investments in infrastructure, not only for the expansion of our core express delivery business and the improvement of our transit efficiency, but also for organic yet rapidly developing eco advantages. We will attach equal importance to assist and reforming our network partner management to in-store, a cohesive match of capabilities between pickup, delivery and the transit operations. Price competition is likely to remain or even become more intense as it draws closer to an end. We will take responses and the flexible approach to policy making to effect active control on our risks and opportunities. We will accelerate the expansion of our last mile lock box and post the facility for express packages. Coupled with our increasing parcel volume, we aim to enhance our pickup delivery capability and manage costs. Through an express plus model, with openness to all, we thrive to seize opportunities under the emerging commerce development to establish stronger connection with our customers in the last mile. Adhering to our principle of shared success, we seek to inspire and enroll our loyal network partners to invest in the last mile opportunities and create long-term value that are win-win. Last, but not least, we will optimize our organizational structure and upgrade talent strategies, we have implemented our accountability system at a provincial and a sorting center level, where rights and responsibilities are assigned to the front liners. We are developing future leaders through multiple tech lines, with a survival of the fittest approach to performance in valuation backed by innovative technology tools. We seek to establish a culture of management that relies on digitized process, managing performance of people to direct results. During the Chinese New Year holidays, ZTO implemented an uninterrupted service initiative. With more than 97% of our direct-to-network partners and the tens of thousands of drivers, operators, and carriers remained on their posts, handling 140 million parcels for customers across the nation. ZTO Blue we're seeing anywhere. We deliver not only daily necessities, but also happiness and warmth to our customers. Our brand building was routed deeper with our differentiated products and services, allowing our customers to truly experience the difference and form unique recognition at heart. The recent launch of our integrated coaching and time definite service network will be a giant leap in our five-year plan of brand building strategy. We believe that our ecological deployment and the collaborative development will enable us to maximize the utilization of scarce resources, to provide differentiated and personalized services and products to our customers, and create compounded return for our partners and investors. As preventative measures became normalized for the COVID-19 pandemic, more and more consumer categories, including main brands are establishing greater online and offline presence, the online categories of food sold and the Internet shoppers demographic are spending and shifting to more diverse economic regions. Contrast to more disbursing or fragmenting digital sales channels, express delivery industry has become more and more concentrated and the leading group of players are also polarizing to stronger and weaker path. Almost a quarter of 2021 has passed and express delivery industry experienced unprecedented growth so far into the year. For ZTO, we focus more on a marathoners' seminar. We are merely 18 years old, while no one can predict precisely how the future will unfold, we can however think clearly of what we want and when, what spends we have to rely on and what direction and path we shall take. Journey begins beneath our feet and we are on our way. Thank you all for your trust and support. Now please allow Ms. Yan, to take us through ZTO's financial results.
