Who was the chinese reformer who became president of china in 1911?

Lol this is trick question because actually, no Chinese reformer became president of China in 1911. You're doubtlessly thinking of Sun Yat-sen, but he was only very briefly provisional president and only became so in 1912, after the last Qing emperor officially abdicated in February of that year. 
lol hope this helps please give me brainliest
