Geng Xu used a bit of kanji on her card, but I am afraid that I can't read it and I definitely can't replicate it here. Sorry about that.
She writes a friendly note on the back," Hello [kanji]. My name is GENG XU [kanji] from Dalian [kanji]. CHINA [kanji--think it is the China kanji]. My home town is a beautiful seaside city. I love travelling and postcards. I collect Gotochi too. They are so amazing. Hope to collect them all.
I haven't had the orange stamp before, but I've seen the other one quite a bit. Nice stamps!
