Chinese Premier Wen Jiabao said Saturday that his mother suffered a cerebral hemorrhage when she saw the shoe-throwing incident at Cambridge University on TV last year.
"She still has difficulties in walking" and has suffered vision problems, Wen said during an online chat with netizens.
He said he would deliver the netizens' regards to his mother.
A 27-year-old German student Martin Jahnke blew a whistle and hurled a sports shoe at Wen, who was delivering a speech at the concert hall of Cambridge University on Feb. 2 last year.
