Is the cheongsam collar high or low?

The cheongsam with high neck and tight tie looks solemn and elegant, but it depends on the posture. A tight high collar for people with slender necks; It will highlight the deficiency of the neck and the collar will be shorter and wider to make up for this deficiency. However, I went to Fuli City to make cheongsam that day, and the master there told me that the collar was high and the neck was long.
