Hi sayaka116,
We appreciate you reaching out through Apple Support Communities! It sounds like you're seeing that your iPhone location is off by a bit in the Find My app. Is this correct?
If so, we want to mention the your iPhone uses a combination of GPS signals, cellular tower triangulation, and local Wi-Fi networks to determine an estimate of its location. This means that the location of your device will be approximate, and may be affected by incorrect location information sent by local networks or cell towers.
Here's more information:
