The board of directors shall keep minutes of the resolutions made, and the directors present at the meeting shall sign the resolutions. As for the organizational form of the meeting, it can be on-site meeting or off-site meeting (such as signature), but the resolution should at least indicate the content of the resolution and be signed by the directors. The time of the meeting can be ignored, but the time when the resolution is formed must be there, otherwise disputes may arise in practice.
