Why are all the TV plays in Singapore in Chinese?

Television stations in Singapore use different languages. Generally, China only introduces TV series of Mediacorp8, which is a Chinese channel, so most of them are in Chinese.

Singapore, formerly known as the Republic of Singapore, or Singapore, Sin Chew or Sing Tao, or Lion City, is an island country in Southeast Asia with a parliamentary political system. Singapore is adjacent to Malaysia across the Johor Strait in the north, Indonesia across the Singapore Strait in the south, and the southern mouth of the Straits of Malacca.
