Thank you, Jack. Hello, everyone. Our overseas business growth momentum continued into Q1 2022 as Q1 gross billings reached $5.3 million, exceeding the top end of our guidance of $4.6 million. We will continue on our pathway of sustained balanced growth and execute our strategy that bring to overseas students' strong value proposition for learning English. Now let me walk you through our first quarter 2022 financial details. Net revenues for Q1 were $9.5 million, representing a decline of 89.7% from the same quarter last year. Net revenues for the company's overseas business and the Mainland China business were $1.9 million and $7.6 million, respectively. Gross margin for the first quarter was negative 14%. Gross margin for the company's overseas business and the Mainland China business were 77.9% and negative 36.7%, respectively. We did not recognize $48 million noncompliant lesson consumptions as revenues for our China Mainland business, but we still recorded the corresponding cost of revenue of $9.1 million. Q1 operating expenses were $20.6 million, a 59% sequential decrease from $50.2 million for last quarter. Q1 sales and marketing expense were $7.1 million, down 81% sequentially. Sales and marketing expenses for overseas business and Mainland China business were $2.0 million and $5.1 million, respectively. Q1 product development expenses were $2.0 million, down 16% sequentially. Product development expenses for overseas business and Mainland China business were $1.1 million and $0.9 million, respectively. Q1 G&A expenses were $11.5 million. Among which, $2.9 million were VAT related to noncompliant lesson consumptions, $2.8 million were accrued VAT and related penalty and $0.8 million were severance costs. Excluding these onetime items from Mainland China business, Q1 G&A expenses would have been $5.0 million, down 27% sequentially. G&A expenses for overseas business were $1.9 million. Q1 operating loss was $21.7 million, where overseas operating loss was $3.5 million and Mainland China operating loss was $18.2 million. Q1 net loss was $21.2 million. Net loss for overseas business and the Mainland China business were $3.4 million and $17.7 million, respectively. Q1 GAAP and non-GAAP EPS were negative $0.95 and negative $0.94, respectively. The company's total cash, cash equivalents, time deposits, short-term investments and restricted cash were $126 million at the end of first quarter. And among which, $7.7 million were restricted cash, which was advances from students under government supervision. Advances from students were $216.6 million at the end of the first quarter. Among which, $6.1 million were for overseas business and $210.5 million were for Mainland China business. The gap between advances from students and cash balances has decreased from $119 million in Q4 to $90 million in Q1. Looking forward to the second quarter of 2022, we currently expect net gross billing of overseas business to be between $7.2 million and $7.5 million, representing sequential growth between 36.1% to 41.8%. We estimate the costs related to the spin-off transaction to be less than $1 million. And excluding the costs related to the transaction, we expect Q2 operating cash flow to be slightly positive. The above outlook is based on current market conditions and reflects the company's current and preliminary estimate of market and operating conditions and the customer demand, which are all subject to change. This concludes our prepared remarks. We will now open the call to questions. Operator, please go ahead.
