Overseas, Twitter and Instagram are equivalents to China's Weibo; since Musheng now has work overseas, it makes sense for her to create a social media account.
After some thought, she didn't reject Rachel's suggestion and nodded, "Alright, I'll set up an account."
China employs a firewall for some of the international social networking sites, but when pitted against the formidable digital prowess of Chinese netizens, the firewall can be somewhat advantageous. There's a saying inside China that the firewall exists to protect internet users abroad; otherwise, if the vast Chinese population were to invade foreign social media, it would be like a storm of blood and fishy wind.
Especially when there's a language barrier.
After setting up her Instagram account, Rachel asked for Musheng's details, followed her immediately, posted a photo, and tagged Musheng.
