Hello, everyone. Baidu Core earned RMB 23.2 billion in revenues and 5.1 billion in non-GAAP operating profit in the second quarter. The resurgence of COVID-19 led to an unfavorable macro environment in the quarter. However, Baidu AI cloud and intelligent driving business maintained their rapid growth momentum as we aligned well with the government's repeated cost for technology innovation.
Especially Q2 revenues from Baidu AI Cloud increased by 31% year over year outgrowing many of our peers, contributing 18% of Baidu Core's revenues in the quarter. That's up from 14% in the same period last year. Further, the operating margin for Baidu AI Cloud improved on both a year over year and quarter-over-quarter basis. Apollo Go completed 287,000 lines in Q2, increasing by almost 500% year over year.
