## What it is
An open dataset of Chinese administrative division codes (GB/T 2260) covering provinces, cities, districts/counties, and towns/townships, distributed as JSON files with latest, historical, and diff data. It is actively maintained and MIT-licensed, with companion widgets for cascading region selection and ID card parsing.

## Use cases
- populate province/city/district cascading dropdowns in a form
- look up Chinese administrative division codes by region
- parse Chinese ID card numbers to extract region info
- query historical changes to China's administrative divisions
- add a region picker to a Chinese e-commerce checkout
- fuzzy search Chinese province and city names

## When to choose
- you need authoritative, regularly updated Chinese administrative division data
- you want cascading region selection in a web form
- you need historical or diff data for division code changes

## When to avoid
- you need administrative divisions for countries other than China
- you need guaranteed up-to-the-minute township-level data, which lags due to data volume
