One thing good about them is that they are very patriotic
people.
A few years back when Singapore hosted China in a soccer
qualifying match, half the National Stadium was packed with PRC
fans sitting at the grandstand area. Their singing of
patriotic songs during the game almost made it look like National
Stadium was the home ground for the Chinese team.
So scary.
