Origin Story
春天来了，万物复苏。田野里，麦苗返青，油菜花金黄一片。山坡上，桃花盛开，梨花如雪。小河边，柳枝轻拂，杨柳依依。一群群燕子从南方飞来，在空中自由飞翔，轻盈地穿梭于花丛之间，时而俯冲，时而盘旋，像是在为春天的到来而舞蹈。枝头上的黄莺也开始歌唱，婉转动听的歌声回荡在山谷里，仿佛在诉说着春天的故事。整个村庄都充满了生机与活力，处处洋溢着莺吟燕舞的景象，人们也感受着春天的美好与希望。
Spring has arrived, and all things are reviving. In the fields, wheat seedlings turn green, and rapeseed flowers are golden yellow. On the hillsides, peach blossoms are in full bloom, and pear blossoms are like snow. By the river, willow branches gently sway, and willows are weeping. Groups of swallows fly from the south, flying freely in the sky, lightly shuttling among the flowers, sometimes diving, sometimes circling, as if dancing for the arrival of spring. Orioles on the branches begin to sing, their melodious songs echoing in the valley, as if telling stories of spring. The whole village is full of life and vitality, everywhere overflowing with the scene of orioles singing and swallows dancing, and people feel the beauty and hope of spring.
