Four corners. Which stars are big up and down and small on both sides?

Could the landlord be talking about Betelgeuse (the main body of Orion)? The following is a starry sky photo for the landlord's reference.

In addition, this vague description will inevitably lead to ambiguity. For example, here, is it an object with a unique shape or a combination of several stars? Even if it is understood as the latter, the answer is obviously not unique. For example, the crow's nest generally conforms to the description of the landlord:

In addition, there are countless ladder combinations arranged in an approximate square in ancient China, such as the four stars in the middle of Su Jing (southwest of Gemini), the potential star (south of Ursa major and part of the little lion) and the mortar star (northeast of Pegasus and part of the scorpion). If the constellations can be spliced together, it will be countless. A classmate of the Astronomical Society loves squares. In autumn, only the brightest second-and third-class stars spell out a pair of square glasses, so the Pegasus quadrilateral is not introduced. Other shots are Milac, Tianchuan III, Tongue Curling V and Lou Su III. This pair of glasses is actually in line with the landlord's question ~
