We have had a week's holiday for National Day as I have mentioned and the campus was quiet. Lovely. Over the weekend the students started arriving back, and one called me. She had a gift from her mother for me. So I met her near one of the class buildings and came back to my apartment.
She gave me a bag full of strange things. I had no idea of what they were. She bit one with her teeth and crunched off one of the "wing'" bits. Inside it is like a potato but is in fact it is some sort of water chestnut.
I am not sure what they are called in English. The students call them Da Lin - but I cannot find any other information.
