# dojo_sector_info — Sector Taxonomy
## Overview
Three-level sector taxonomy (L1 industry → L2 chain → L3 sub-sector) with bilingual Chinese/English names and definitions.
## Files
| File | Description |
|------|-------------|
| `data.parquet` | Taxonomy tree (one L1 row each; L2/L3 nested in `children`) |
## Key Fields
| Field | Description |
|-------|-------------|
| `id` | L1 sector ID |
| `name` / `name_alias` | L1 English name / Chinese alias |
| `description` / `description_alias` | L1 English / Chinese definition |
| `children` | JSON array nesting L2 → L3 nodes (`id`, `name`, `name_alias`, `description`, `level`, …) |
| `symbol` | Placeholder (e.g. `ALL`), not a stock ticker |
### children Node Shape (L2 / L3)
```json
{
"id": 13,
"name": "Consumer Electronics",
"name_alias": "消费电子",
"description": "...",
"description_alias": "...",
"level": 2,
"children": []
}
```
## Scale (reference)
~**11** L1 root rows; hundreds of L3 paths when the tree is expanded.
