Good day ladies and gentlemen. Thanks for participating in our discussion of The9 2020 financial results and our recent developments on the cryptocurrency mining business. For the year-ended December 31, 2020, net income attributable to holders of ordinary shares was [RMB397 million] or [US$60.8 million], compared to a net loss attributable to holders of ordinary shares amounted to RMB190.6 million or US$29.2 million for the year ended December 31, 2019. The net profit of the year ended December 31, 2020 was mainly attributed to the gain on disposal of subsidiaries, which collectively held [indiscernible] and an office building located at Zhang Jiang, Shanghai. Let's turn our focus to our recent development on the cryptocurrency mining business. In January 2021, we entered into a co-operation and investment agreement with several investors, including Mr. JianPing Kong in the cryptocurrency miningindustry in anticipation of developing our cryptocurrency mining business with the assistance of these investors. We issued certain ordinary shares and warrants to the investors. The warrants are divided into four equal challenges, which are exercisable subject to the market capitalization of The9, ranging from US$100 million, US$300 million, US$500 million, and US$1 billion between certain time period. In February 2021, NBTC limited, a wholly-owned subsidiary of The9, signed a strategic cooperation framework purchase agreement with Shenzhen MicroBT Electronics Technology Company Ltd., the manufacturer of WhatsMiner Bitcoin mining machines. We paid a deposit of US$1.4 million and obtained the right of first offer to purchase 5,000 WhatsMiner Bitcoin mining machines from MicroBT within one-year. As of today, we have completed two batches of purchase and bought 922 WhatsMiner machines, with an approximate hash rate of 66PH/s. These WhatsMiner machines have already been deployed. In March 2021, NBTC signed a Bitcoin mining machine purchase agreement with Bitmain Technologies Limited. Pursuant to the purchase agreement, we will purchase 24,000 AntminerS19j Bitcoin mining machines, which are scheduled to deliver starting from November 2021, for a total consideration of US$82.8 million payable by installments according to the agreed time schedule. The first installment of US$16.6 million has been paid. In February 2021, we entered into purchase agreements with five Bitcoin mining machine owners to purchase Bitcoin mining machines by issuance of its ordinary shares. The9 issued an aggregate of 26.9 million ordinary shares, equivalent to 0.9 million ADSs at US$11.18 per ADS in exchange for 26,007 Bitcoin mining machines, with a total hash rate of approximately 549PH/S. In February 2021, we signed six legally binding MOUs with six Bitcoin mining machine owners to purchase Bitcoin mining machines by issuance of ordinary shares. As of to date, we have entered into definitive purchase agreements with five Bitcoin mining machine owners and The9 has issued an aggregate of 3.8 million ordinary shares equivalent to 0.1 million ADSs at US$23.35 per ADS in exchange for 8,489 Bitcoin mining machines, with a total hash rate of approximately 156PH/S. In March 2021, we signed three legally-binding MOUs with three Bitcoin mining machine owners to purchase Bitcoin mining machines by issuance of ordinary shares. According to the MOUs, The9 should issue to the sellers approximately 5.9 million ordinary shares, equivalent to 0.2 million ADSs and US$38.51 per ADS in exchange for 10,252 Bitcoin mining machines, with a total hash rate of approximately 192PH/S. In February 2021, we signed a framework agreement with a Filecoin mining machine vendor to purchase Filecoin mining machines for US$10 million. In February 2021, we entered into a standby equity distribution agreement with YA II PN, LTD., a limited partnership managed by Yorkville Advisor Global, LP pursuant to which The9 is able to sell up to US$100.0 million of ADSs solely at our request at any time during the 36 months following the date of the agreement. As of today, we have not started to request funding from this equity line. As of today, our deployed Bitcoin mining machines are contributing a total hash rate of approximately 693PH/S. Under this current hash rate, we have rewarded 3 Bitcoins per day. As of today, we have been rewarded 126 Bitcoins. Based on the Bitcoin mining machines currently owned by us and taking account to the mining machines purchase agreements we have signed, assuming we do not sign any new purchase agreement and assuming global hash rate does not increase, by October 2022 our Bitcoin mining machines are expected to contribute a total hash rate of approximately 3,558PH/S. Under this hash rate, we are expected to be rewarded approximately 15 Bitcoins per day. The cumulative Bitcoins reward is expected to be approximately 5,200 Bitcoins. Other than Bitcoins, we are also actively engaged in the mining of Filecoins. As of today, we have executed US$1.1 million purchase of Filecoin mining machines under the framework agreement with a Filecoin mining machine vendor. Currently, we own an independent node on Filecoin blockchain and 8 Pebibyte of effective storage mining power in the Filecoin network. Assuming global hash rate does not increase, by August 2022 this 8 Pebibyte of effective storage mining power is expected to generate approximately 200,000 Filecoins for us. However, since the hash rate of the whole Filecoin network is increasing continuously, the actual reward to us will be less than 200,000 Filecoin. And actually as we just announced hours ago, we just signed a Filecoin mining machine purchase and hosting agreement amounting to approximately US$2 million with another Filecoin mining service provider. When both agreement are fully implemented, we expect to have a total of more than 80 Pebibytes of effective storage mining power in the Filecoin network. We will continue to invest in the Filecoin mining machines according to the growth of Filecoin's market value. So, thank you for listening to our presentation today. At this time, we will take questions. Operator, please.
