Email Americans are much more like using email than Chinese. Although Chinese are using email more often than before, email is more about dealing with very formal working situations. For less formal things, we use WeChat a lot, which is a widely spread chatting software. WeChat is like WhatsApp in China, but it allows people to build chat groups, and it is not popular among young people, almost every Chinese has a WeChat account. So, friends can have a chat group, families can share a chat group, and teachers and students can be in the same chat group. As long as you have a cell phone which is connected to the Internet, you can receive from and send to messages to a bunch of people immediately at the same time. For example, when I was in China if my lab members were going to have dinner together, messages would be sent in the chat group, and everyone could discuss the location, time and anything else rapidly. Even there was some last-minute change, we could update in the chat group and would not worry about that someone might forget to check the email. However, when I had lab social events in America, every information was collected and transmitted by email. It's really less convenient than what we did in China, and it would be much more comfortable if a happy social event email didn't coexist with tedious working emails in my mailbox. I mean, I really would love to separate my life from work!
