You understand correctly. When heating, point the raft to the left of the white dot. However, after cooking, if you are not in a hurry to eat, you don't need to move the raft and let it exhaust naturally. Unless you are in a hurry to eat, you can raft at Xiaobaidian to exhaust quickly. But remember, if it's porridge and soup, don't move the raft in a hurry, or soup will escape from the exhaust port and hurt people. You can only open the lid until it cools naturally.
