2012Year6month11日, Mark, the younger brother of US President Obama·Obama·Di Shanjiu visited the w88 casino and gave a speech. During the question session, he called his brother Obama a“People who are good at planning”，“Never work casually without a plan”, but as a professional pianist, Mark obviously thinks that he is musically superior to his brother.

It is reported that this is Mark’s first public speech at a Chinese university. His personal calligraphy demonstration also won bursts of applause from the audience. In the afternoon of the same day, Mark arrived in Beijing in a low-key manner. He visited the college student volunteers at the charity sale and had a cordial exchange with international students from the International College.
