With the ultimate goal of pairing up every US county with a unique Chinese county for prayer, a few states have to be «subdivided» so that the county numbers and/or population match up well.
In the case of Maryland, the 8 counties closest to Washington D.C. are joined up with the Capital and matched up with China’s capital, Beijing, for prayer.
The remaining 16 counties of Maryland match up perfectly with the 16 counties of Tianjin, a small province/city located just east of Beijing along China’s near-northeastern coast.
