1. Purpose
This tool is used to obtain region location codes required for weather data retrieval. By querying region information, you can get the corresponding administrative division code (adcode) for use by the device’s weather module.

2. Device Configuration
The device uses the adcode obtained through network positioning or manual input to achieve accurate region association and weather data retrieval.

3. Positioning Method
In most cases, automatic network positioning on the device is sufficient. When network positioning is inaccurate, you can use this tool to manually query and specify the exact region.

4. Supported Regions
Currently, only region codes in China are supported. In the future, support for other countries and regions will be gradually expanded based on device usage and geographic distribution.
