This brings back memories of a visit some 20 years ago to Moganshan （莫干山） park in northwest Zhejiang province, China. There we ran across an amazingly lively and intelligent 11 year-old boy, who lived with his family nearby. We asked his mail address, and he wrote it down full: 莫干山 大树下 [Mt. Mogan, under the big tree]. Asking around, this was indeed a valid postal address.
