Before going to lunch Elena changed her dress and wore a red hanfu with golden designs on it. She also put on a hairpin made using a beautiful purple coloured magic stone. And as the final touch, she drew a symbol of five pink flower petals on her forehead. It was actually a special symbol representing that she was loved by the Goddess Tiandi herself.
But for Elena this symbol had a different meaning. By using this symbol she was telling Tiandi that Elena appreciated her quite a lot and it was a great accomplishment for Tiandi. Without her acknowledgement no one would be able to complete the drawing of this pattern, so would be an undeniable proof of her close relation with Tiandi's divine realm.
