Sorry I can't read the script. However it could be two things a multi graft on one plant or color variations because of how long the flower has been open. Most will fade over time. Is it posible that you could translate for us that are too lazy to find the dictionary?

It is said to be a breakthrough of grafting. These are in LuoYang  a formal TP center. However, the news does not say much about the technique. There are other interesting things, such as one TP with 180 flowers, 20" diameter flower, 10 tall TP with large white flowers, century and half  150 year  old TP, etc.
