I stumbled upon an impressive family of Chinese IDNs. All these IDNs belong to Gērùn 歌润, a Company that specialises in Cork products such as flooring and wall panels. The difference between these IDNs is in the initial two characters which are the names of the cities in which this Company has stores.
The website adapts content according to the IDN used to access the site. On the contact (联系方法) page there is a store location map according to the city specified in the IDN. Apart from Yìwū the maps used are Google maps.

Update: I found nine of the above addresses using the search engines site operator. I noticed the pattern and was thus able to group them into a family. Recently I discovered the Company's Sina (新浪) blog.
The address I had not found with the search engines was ㊉ Zhèngzhōu.
