Dear Mark,
I'm writing to share my experience with you.
As you know that, dumplings, which are unique to China, are loved by Chinese and nearly all vegetables can be used as fillings. Besides, chopping vegetables into piece is tiring, especially when there is a large family to feed. Recently, I found an amazing device that get around this problem. It is a device mostly made by inexpensive, plastic-like parts. All you need to do is put the vegetables into the box, closing the lid and turn the handle. In less than two minutes, the vegetables were ready.
I am grateful to the inventor who came down with this clever idea, which makes my life conveniently. Have you ever impressed by small devices? I'm looking forward to your reply.
Yours,
Li Hua
