Just spotted the following tweet:
It is great to see some use of Chinese in his tweets. Not everyone who follows politicians is going to have English as their first language. One of the things taht Twitter lets candidates and MPs do is build followings in their own community and focus attention on them. So using methods that will connect with them, and make it easier for them to understand and engage is a good thing. The Maori party are using lots of Te Reo in their social media push, so why not Chinese for a Chinese MP to connect with the Chinese community?
