What does it mean to move up in the yellow calendar?

Meaning 1: refers to the relocated people. Proper migration in the yellow calendar means that this day is suitable for moving. However, migration usually does not mean moving into a new house, but because of some external factors, people have to move.

Meaning 2: refers to the movement of goods. In geomantic omen, the placement and orientation of furniture are particular, so if you want to move large furniture or add new furniture, you must be optimistic about the date of moving and staying. Therefore, the migration in the yellow calendar also means that this day is suitable for the movement of important items.
