Verify both Dumplings and both sides of the offer; use gifting only when you expect nothing back.
Trading and gifting exist, but the exact current UI requirements are not verified; no authoritative value list or trade calculator is published. Use safe pre transfer checks and a fair comparison checklist: confirm the exact Dumpling, apply value source rules, explain source confidence by date and method, repeat both sides, avoid scams and off-platform promises, and stop when the in-game transfer interface is unclear.
