Your Eyebrow and your Siblings
There is a popular Chinese saying, “Eyebrow longer than the eye, sibling 4, 5, 6”.
The saying implies that if your eyebrow is longer than (the width of) your eye then you will have many siblings.
In Chinese Face Reading, the eyebrow and the region near it falls under the Sibling palace. It denotes amongst many things the quality of the relationship that you have with your sibling (includes cousins and business partners).
If the eyebrow is long and orderly, then the person is on friendly terms with his siblings and is likely to have a large family. On the other hand if the eyebrow is short then he is likely to come from a small family and may have problems with siblings!
