How to build a one-centimeter seam on a brick drywall?

If the brick wall requires a brick joint width of 1 cm, then the brick joint of 1 cm can be increased according to the height of the red brick, with a total height of 7 cm. At this point, the tile trade union hangs a horizontal line on both sides at the same time, relying on this horizontal line to control the height and complete the brick joint height required for bricklaying. And so on until the whole wall is completed. This wall-building method can be said to be the traditional method of the wall-building master, which has been used for a long time. But now the high-rise buildings are cast-in-place reinforced concrete walls, so there is no need to build bricks.
