Protest Against Chen
BBC NEWS | Asia-Pacific | Taiwan leader faces mass protest
Organisers say more that 200,000 people joined Saturday's rally outside the presidential offices in Taipei - but police put the number at 90,000.
The BBC's Caroline Gluck, at the scene, says it is a sea of red.
There are four big red balloons, representing righteousness, integrity, prosperity and honour.
The protesters say these virtues have been lost in today's Taiwan, and Mr Chen should stand down.
