This is a wooden calendar I bought during my trip to Bali 3 years ago. Now this calendar blocks has been my boy's toy. The calendar date shows May 13th. Back in history, it is something happen to our city Kuala Lumpur.
On May 13, 1969, one of the worst racial riots in Malaysia took place in Kuala Lumpur. May 13 Incident was a riot between the Malays and the Chinese who were dissatisfied with the socio-political situation at the time. The riot resulted in the deaths of 196 people, and led to a major reform in the country's economic policy. ~ taken from Wikipedia
It is still a sensitive issue to brought up till today. I still remember when I was young, parents told us not to mention or open up to discuss about 513 in the public or we will get caught.
