With the arrival of night, the sky became deep sapphire, and the outline of Hagia Sophia became more and more clear in the night. Suddenly, a strange light flashed over the church, and then, a huge virtual shadow of Santa Claus slowly emerged, suspended above the dome of the church. The virtual shadow of Santa Claus is unusual. It emits a faint blue light, as if it were made up of countless flashing ice crystals, giving people a warm and mysterious feeling. The texture of his beard and clothes is looming in the light and shadow, as if carved by snow. His eyes are shining kindly, as if guarding the city and bringing people festive blessings and warmth. Around the virtual shadow, snowflakes seem to be attracted by some mysterious force and begin to rotate and dance around Santa Claus, forming a huge snowflake vortex. Against the background of virtual shadows, these snowflakes seem to be endowed with life. They shine with colorful light and complement Santa Claus' blue light, forming a fantastic and beautiful picture. Around the church, people stopped in a hurry and looked up at this incredible sight. The children's eyes were full of surprise and joy. They cheered and jumped as if they saw the real Santa Claus. Adults were also attracted by this fantastic scene, and their faces showed a long-lost smile, as if they had returned to their childhood and relived that innocence and happiness.,European architecture
