Yanwen tracking URL from a tracking number

Yanwen (CN) tracking numbers follow this format: YW or YANWEN prefix + alphanumeric (10-25 chars). ShipShim detects the carrier from the number and returns the direct tracking link.

Example: number in, tracking URL out

Example tracking numberYW88888888
Tracking URLhttps://www.yw56.com.cn/en/tracking?no=YW88888888

This format is distinctive, so ShipShim identifies Yanwen from the bare number — no hints needed.
