Thanks to Connie for card showing Nyonya culture in Malacca. Nyonya is Chinese descendants who adopt local culture and way of living and speak local language in their daily life.
"Peranakan Chinese or Straits-born Chinese are the descendants of Chinese immigrants who came to the Malay archipelago including British Malaya (now Peninsular Malaysia and Singapore, where they are also referred to as Baba-Nyonya) and Dutch East Indies (now Indonesia; where they're also referred as Kiau-Seng) between the 15th and 17th centuries.
Members of this community in Malaysia address themselves as "Baba Nyonya". Nyonya is the term for the women and Baba for the men. It applies especially to the Han populations of the British Straits Settlements of Malaya and the Dutch-controlled island of Java and other locations, who have adopted Nusantara customs — partially or in full — to be somewhat assimilated into the local communities. Many were the elites of Singapore, more loyal to the British than to China. Most have lived for generations along the straits of Malacca. They were usually traders, the middleman of the British and the Chinese, or the Chinese and Malays, or vice versa because they were mostly English educated."
