Literature Reference: In mid-month, the icehouse opens, the pure heart feels the emperor's grace. Cold beauty sits on jade, bright colors emanate from red pillars. The accumulated purity grows with the wind, the emptiness shines towards the sun. From afar, the windows feel cold, up close, it reflects the clarity of the crown. In hand, the light becomes clearer, in the hall, its nature is light. Only in auspicious times can it be presented, thus expressing sincerity. Source from 'Jian Bing'.
