Rather than typing with two hands eyes glued to the screen which is terrible given the number of accidents we’ve had from walking while texting or the often fatal driving while texting, the Chinese do this.
They use voice chat as the main method. This is the norm on WeChat, the messaging app with over 500 million monthly users, according to Quartz.
Push-to-talk messaging’s growth in Asia is widely attributed to the difficulty of typing in Chinese. Vocal messaging people is simpler and more personal. It is also louder.
Specifically in China, the custom is more widely accepted than in other Chinese-speaking countries like Taiwan, where loud voice messaging in public would be frowned upon for being rude.
