2. From the chosen province, lookup ward code

For example, we want to look into Đắk Nông province.

$ businessowner-retriever codes 606
┌──────────────────┬───────┐
│ District         │ Code  │
├──────────────────┼───────┤
│ Huyện Cư Jút     │ 60603 │
│ Huyện Krông Nô   │ 60605 │
│ Huyện Tuy Đức    │ 60617 │
│ Huyện Đắk Glong  │ 60615 │
│ Huyện Đắk Mil    │ 60607 │
│ Huyện Đắk R'Lấp  │ 60611 │
│ Huyện Đắk Song   │ 60609 │
│ Thị xã Gia Nghĩa │ 60613 │
└──────────────────┴───────┘

Try Cư Jút district, with code 60603:

$ businessowner-retriever codes 60603
┌────────────────────┬─────────┐
│ Ward               │ Code    │
├────────────────────┼─────────┤
│ Thị trấn Ea T-Ling │ 6060301 │
│ Xã Cư Knia         │ 6060305 │
│ Xã Ea Pô           │ 6060303 │
│ Xã Nam Dong        │ 6060309 │
│ Xã Trúc Sơn        │ 6060315 │
│ Xã Tâm Thắng       │ 6060313 │
│ Xã Đắk DRông       │ 6060311 │
│ Xã Đắk Wil         │ 6060307 │
└────────────────────┴─────────┘

3. Retrieve list of business owners in that ward

Run businessowners subcommand, passing ward code, and specify output file name. The program produces data in CSV file.

$ businessowner-retriever businessowners 6060305 -o xa_cu_kinia.csv
Wrote to file: xa_cu_knia.csv

Notes

• The server of data source, www.gdt.gov.vn, has access throttling. After an amount of data retrieval, it will block us. You should take a rest, before continuing, or finding a proxy to fake your IP address.

• On Windows, please run the program inside ConEmu. It is because BusinessOwner Retriever has an issue with character encoding in PowerShell console, which I (Quân) can't resolve (I'm just a Linux programmer).

• The produced CSV file is in UTF-8 character encoding but it is not automatically recognized by MS Excel (maybe because of lacking BOM characters). In Excel, you need to do some configuration steps, manually, to make it display correctly the file. If you are tired from that, I recommend to use LibreOffice, which detects CSV better.
