To address the issue of missing data for districts and communes in Hanoi, Vietnam, when using the CountryStateCity API, it's important to consider several factors that could be contributing to this problem:

1. Data Completeness: The API might not have complete data for all districts and communes due to incomplete data entry or updates. It's crucial to ensure that the database behind the API includes comprehensive and up-to-date information on Vietnam's administrative divisions.

2. Query Filtering and Script Logic: The way data is fetched and exported could inadvertently exclude certain districts or communes. Review the script and query logic for any conditions or filters that might be leaving out the needed data. Ensure that the categorization of data aligns with Vietnam's administrative structure, particularly for Hanoi's districts and communes.

3. Database Schema: The issue might also lie in how the database schema is designed, especially if districts and communes are not adequately represented or if there's a mismatch in categorization. Direct database queries can help identify if the data is present but not being retrieved correctly.

4. Alternative Data Sources: If the current database and API do not provide the required granularity, consider using alternative data sources that include detailed information on Vietnam's administrative divisions.

By focusing on these areas, you can better diagnose the cause of the missing data and find a suitable solution to ensure that districts and communes in Hanoi are accurately represented in your queries.
