What are the three major lines?

The three patterns specifically refer to cross pattern, star pattern and island pattern.

[1] The cross pattern is formed by crossing two "short lines" on the palm, and its good and bad meanings vary according to the position of the palm.

[2] The star pattern is formed by crossing three or more "short lines" on the palm, and the meaning of good or bad is also different according to the part that appears on the palm.

[3] The island pattern appears on the "five major line patterns" of the palm, which usually has a bad meaning, depending on the line where it is located.
