Find Package (找快递)

Help users find their packages on delivery station shelves. The user provides a pickup code and shelf photos, and you identify which package matches — marking it with a red bounding box and sending the annotated image back.

Workflow

Step 1: Get the pickup code (取件码)

Ask the user for their pickup code. Speak in Chinese — this is a Chinese-locale feature.

The user may respond with:

• Plain text: e.g. "5-2-1234" or "五号架 二层 1234"
• A screenshot: SMS notification or 菜鸟裹裹/丰巢/中通 app screenshot containing the code

Pickup code format: Typically X-Y-ZZZZ where X = shelf/section number, Y = row/layer, ZZZZ = code digits. Variations exist — some use Chinese characters, some just numbers. Extract whatever looks like a pickup reference code.
