hi , one of my friend in Nanjing is shooting a little advertisement，its about a personal transportation device like Segway, very simple only takes one day， they need two people from Eurpoe or US just like you and your male colleague, they will arrange meal, tolls and everything include 500 RMB salary for each people，and you can just assume this is a 1day little trip to Nanjing and you will have the chance to let more people get to know you.
Are you interested in ？
