Seeing red over green

To review

The First Experimental Elementary School of Weiyang district in Xi'an, Shaanxi province, hit the headlines for requiring students with a poor performance to wear a green scarf, distinguishing them from the good performance of the red scarf, a symbol for the Young Pioneer organization.

We say

It is really improper for the school to separate children into different classes, upper and lower, by colored scarves. Maybe the school managers should take another course in the psychology of education.
