Throwing an idea out of my head :'3
When I saw the fourth part of "Kung Fu Panda" on the eighth or 15th of March, I touched on one quote from Zhen: «Every step leaves a footprint, no matter how small.»
I don't know why, but after this quote, I remembered about the trolls, or rather about the BroZone band, when they almost managed to achieve Perfect Family Harmony before the band broke up for 20 years.
Then I thought that it was quite possible that the remnants of such powerful magic had not disappeared, but remained on the characters and, in part, could demonstrate the remnants in the form of an aura. However, the only condition is that they enter a certain phase: they sing, dance and, of course, remain themselves (And the deeper they fall into such a phase, the brighter the aura).
Of course, a single type of magic is not as powerful as with PFH, when the family works together; but it is able to attract the attention of the audience and, quite possibly, treat some scratches/abrasions/wounds.
