In China, at least at SJTU, everyone uses We Chat for everything. No one texts and no one you know will send you an email. All attachments, files, photos, etc. will be sent to you via We Chat.
Also, all personal communication is via We Chat. Almost all of that is written rather like texts in America. We Chat has hundreds of little cartoon characters that you can use to send messages, though, which texting doesn’t have. Our emoji are small and limited compared to all that We Chat has.
You can put We Chat on your computer then scan the code on your screen using your phone. That’s how you open your We Chat account on your computer. Then you can upload any files from your computer into We Chat, and We Chat to computer.
I have been here 2 months and finally put We Chat on my computer. The staff at SJTU can now work with me smoothly since they don’t have to email me things anymore. They do send email to all their foreign contacts, but if they see me in a meeting, their brain automatically files me in “We Chat” so even if I ask for an email, they send me a We Chat.
I also have two bike accounts, so I can scan the bar code of Ofo bike or Hello bike when I want a bike, which I use daily now since my food has not healed. You can pay per month, or 15 cents per ride for these. There are constant ads on them. I am learning the ways of Chinese advertising: every time you scan a bike to rent, that is when it sends you to another ad. I am getting faster at closing the ads and going back again to scan the bike. So scan twice, after seeing at least 3 ads. Nevertheless, I love riding a bike in China. Well, the bikes are comfortable. The rules for who goes where are non-existent. Maybe that is why the speed to drive here is slower than in the U.S.?
