One China policy and One Taiwan Policy and everyone will be happy. Taiwan President Cai visit is definitely a historical event with the reunion of the ROC and the US. Many supporters of Taiwan all across from all walks of lives and from all ages plus all races. Taiwan or ROC flag is very popular in the US and no one likes the mainland Chinese flag except certain portions of people who are from mainland China. Diverse voices are so important and not just one official voice.. Democracy is important, local presentation is a must and protesting is part of a free speech. Democracy is not free and guess Taiwan President won this round.
