You should think carefully about what you mean by "short" or "long", and how to determine what is long and what is short? Because this is unclear, the examiner will bring it up when reviewing, and the examiner will reject your application for this claim because this meaning is unclear.
What shall we do? You should indicate the meaning of "long" or "short", for example, the length of A on the H-shaped base is shorter or longer than that of B.
