All right, thank you everyone for joining us on the call today. In Q1 2022, we witnessed the growth in both the China and overseas markets. Total sales volume was up 9.4% year over year. The China market has a volatile quarter mainly caused by the COVID outbreak and a city lockdown that lasted over a month in Shanghai and in Changjiang Delta region. We had a strong opening in China with sales volume growth of 91.6% year over year in January and February. However, in March our China sales performance was adversely affected by the COVID outbreak due to the retail lock downs as well as the manufacturing and the logistic disruption for nearly two weeks. And we experienced 24.1% decline year over year in March. Despite the decline in March, we still had a moderate positive growth of 3.0% year over year in China market in Q1 due to the strong performance in the first two months. Now turning to the international market, we’re seeing a solid growth in the overseas market despite the manufacturing disruptions. Total sales volume outside China reached 14.7k marked 193.7% year over year growth in Q1. The solid growth was a result of our expansion of new product categories sold in Europe and North America. We newly launched kick scooters were tested to be a success in the two-market mentioned above. In this quarter, we sold nearly a 5000 electric moped and almost 10,000 kick scooters.

In Q2, we're shifting the focus of product portfolio expansions of our product performance improvements and the two redefine classics bringing back the improved versions out of our some of our top selling models of MS in Niu Plus series. Being the leader of the smart two wheelers, we continue to improve smart functionalities across our product portfolio. So allow me to go into detail one by one. First, we saw sharp growth in the light electric motorcycle market as our GOVA C3 being well received keep by the market was released last year. So capture this gross will release GOVA G6 at the end of March. The G6 is designed with upgraded battery capacity and it has a range of over 100 kilometers on single charge price that RMB3,999 to RMB4,309 as a male offerings. Another trend we didn't want to make this growing market of the female electric moped and electric bicycle users, we’re well aware of the demand and the purchasing power behind this previously negative market segment of the female scooter users. We launched the GOVA C0 earlier last year as the entry level product specifically for female users. Now this year, we launched a GOVA C3 March as a model priced at RMB4,000 plus. It comes the multiple pastel colors and it is designed with a specialty headlight that really makes the design stand out. On the performance side the GOVA C3 also has a dry range of maximum 100 kilometers. The biggest highlight of the GOVA C3 is the improvement of user experience is the equivalent smart lock and dynamic mode to assist riding uphill, making the writing experience easy and enjoyable. The stylish design the user centric writing experience created a unique selling proposition in the market. Besides a two Niu mid GOVA product we also released GOVA C series which is another addition to the GOVA product line that continues GOVA urge on design with creative color combos for the entry riders. We introduced C0 products entry level price from RMB2,499. And there was more mid end GOVA B Series model to come later this year.

The newly released to mid end GOVA product C3 and entry level go up easier well received by the market accounting for almost 18% of sales in the first month of the rollout. This again demonstrated our ability to create attractive and comprehensive product in the mid end market segment. I'll come into Q2, we’re releasing some upward version of the new electric bicycle products such as MFCU plus with a 20% performance improvement. Although we're bringing back our alumni use classic electric motorcycles of M1 and M plus, we find with new features such as longer dry range and upgrade smart function.

Those intelligent features into make the writing experience smart and easy for our users. This new product offerings and functional upgrade not only helped to drive sales growth but also helped us to improve the product for the gross margin. We all know that the sharp rise in the raw material price, especially the 40% plus price hike in the lithium-ion battery costs has put a tremendous pressure on our gross margin. Given the lithium-ion battery accounted for 35% to 40% of our bomb cost. This was the main cost for our gross margin drop in Q1, an impact would be even bigger in Q2 since some of the raw material price increases are fully recognized in Q2. Now by launching a new product and integrating new features to improve the performance of our existing products will increase the perceived value of our users and are able to sell the product at a premium price in order to close the gap in gross margin cost by the rising materials. Now as we grew up product portfolios, we also expand our sales network in Q1 2022, we opened about 140 new branded stores in China totaling to 3248 stores throughout China.

Our branding and the marketing operations we actively promote our brand as a global leader in urban mobility industry, brand awareness and recognition from market we operate and create a long-term fuel for our company's growth. Now looking forward to Q2 ‘22. It is no doubt a very challenging period for us given the uncertainty caused by the resurgence of COVID-19 China. As of May 2022, quite some major cities have been in full partial lockdowns which adversely affect the consumer spending in all categories with no exception to the demand of two-wheeler vehicles during the lockdown period. We are particularly impacted our sales are highly concentrated in the top tier cities where the COVID restraints are more rigid. In addition, we continue to experience supply chain disruptions at some of the key suppliers are in sharp high visibility. The slowdown in manufacturing and logistics has affected our market performance globally. While the market demand US China faces uncertainties new Q2, our diversified growth strategy put in place since last year has trying some lights.

The to be launching electric bikes products will further strengthen our position at the urban mobility brand.

Now we're also confident in our rebound in the sales in China Post the COVID-19 situation as the same trend observed in 2020. Now in the cities that have been hit by COVID, even though the fields are being hit temporarily. Now traveling with personal scooters appear to be recommended sometimes even as the only form of transportation in cities. For many riding a scooter is safer and easier transportation method and is even recommended method by local community officials. So expect to see a need for electric scooter and bicycle riding with the COVID easing in the coming quarters. So although Q2 will be a challenging quarter for us. Now with our new product offerings in pipeline for both, the China market and the international market, we're still optimistic for the entire year of 2022. Now, I'll turn the call over to Fion, our CFO to go through the financial results.
