Dear Lina,
I am glad to write to you to talk about the deadline about our event planning for May day. As we decided before, we are responsible for half of the planning, respectively. Up to now, one week has passed and two thirds of my part has done. How is your progress? In view of that several days should be spare to combine our plans and discuss the details, what do you think of finishing it in another five days? If you have anything needs to be helped, do not hesitate to tell me and I am happy to give a hand to you.
Keep your excellent work!
best,
Bing
