Liz had a nice view of the city skyline from her apartment. In her neighborhood, she could find wet markets and bazaars, where she could purchase fresh produce and goods for the house. And, if eating at home wasn't desired, Liz could simply walk around the corner to find cool restaurants and inexpensive "street food."
Shanghai is home to 20+ million people. There's also quite a demand for English teachers. If you have an interest, do like Liz, go live and work in Shanghai for a year.
