From the book, From Third World to First, this is what LKY of his first visit to China in May 1976:
“They had officials in their team who spoke every language and dialect we did. Whether we spoke Hokkien, Malay or English, they had officials who had lived in Southeast Asia, or had served in Indonesia for many years, and spoke Malay, Bahasa Indonesia or Hokkien like natives, and could eavesdrop and understand us. So we could not switch language to cut them out.”
That’s why Singlish is so important. Hahaha!
