Why did Singapore become independent from Malaysia in 1965? How many Malays immigrated to Singapore?

It’s not that Singapore breaks away from Malaysia, it’s that Malaysia doesn’t want Singapore! Back then, after World War II, the Malay Peninsula (Western Malaysia), plus Singapore, plus Sabah and Sarawak in East Malaysia, formed the great Federation of Malaysia. However, soon the Malays and Chinese had a lot of unhappiness because of their different ideas of governing the country. In addition, Lee Kuan Yew's superior ability overshadowed the Malay Prime Minister. Some people were worried that the entire Malaysia would be ruled by Lee Kuan Yew's Chinese people in the future, so they quickly found some reasons, caused some troubles, and kicked Singapore out of the federation. . At that time, in order to persuade Singapore to become independent, Malaysia also offered many preferential conditions, such as promising to supply fresh water for 200 years, etc. Lee Kuan Yew even shed tears when the country became independent.
