Because of the 1886 workers' riot, good we have an extra holiday in Singapore, and many other countries. May day is not observed in US, even it originated from Chicago. China goes even further. May day is now a week of holiday, to boost the tourism and related service industries. China used to award excellent workers with May Day Work Medal, which is a very high spiritual honor. We went to IKEA again. Because it is a furniture store for working class, it fits well for this holiday:p. So many people. Long queue to underground parking. Long queue to enjoy the IKEA restaurant. Long queue to play the kids bubble yard.
