Shang chi questions arised

    Question about Shag chi movie are

Why colour of ten ring changes from blue to yellow or orange ? 

1: maybe because of 

    good person and evil person

2: maybe Wenwu had mastered the ten rings or had been on higher level of mastering the ten rings and Shang chi is at first level or zero level. Just like computer games in which weapon is upgradable according to players level but here only colour changes. 

                  Origin of ten rings

As I have searched on Internet, I have found somethings and here are my conclusion. 

Ten rings were taken from dragon like alien specie's crashed spaceship. Ten rings were used as power source for the engine. Maybe the dragon in the end of movie is that alien specie. 

         

              Ten rings acting as beacon. 

   

If it is a spaceship part ? Then it must be sending message to creators of the spaceship about " spaceship had been crashed and send help ".
