【正文】 s Day! in shops, hotels and restaurants. But few young women will mark the festival with their boyfriends, or take part in traditional activities to pray for cleverness. A largescale 。s Day on February 14, characterized by bouquets of roses, chocolates and romantic candlelight dinners, than they do about their homegrown day for lovers. Even Qixi is nowadays referred to as the Chinese Valentine39。s misery, the cow told him to turn its hide into 蕪湖職業(yè)技術(shù)學(xué)院畢業(yè)設(shè)計(jì) a pair of shoes after it died. The magic shoes whisked Niulang, who carried his two children in baskets strung from a shoulder pole, off on a chase after the empress. The pursuit enraged the empress, who took her hairpin and slashed it across the sky creating the Milky Way which separated husband from wife. But all was not lost as magpies, moved by their love and devotion, formed a bridge across the Milky Way to reunite the family. Even the Jade Emperor was touched, and allowed Niulang and Zhinu to meet once a year on the seventh night of the seventh month. This is how Qixi came to be. The festival can be traced back to the Han Dynasty (206 BCAD 220). Traditionally, people would look up at the sky and find a bright star in the constellation Aquila as well as the star Vega, which are identified as Niulang and Zhinu. The two stars shine on opposite sides of the Milky Way. Customs In bygone days, Qixi was not only a special day for lovers, but also for girls. It is also known as the Begging for Skills Festival or Daughters39。s largest virgin forest, and known for its spring and ecological environment, Arxan is marveled at by many tourists as the purest land on earth. You cannot miss out the Autumn of Arxan. It is definitely the best with brightlycolored scenery full of emotions. Autumn in the northern part of the country es earlier than the South. A September rain followed by the footprints of Autumn brings more colors to the once emerald green mountain and blooming grassland. Shutterbugs flock to see for themselves the marvel of splendid colors around the mountains and waters, many of whom have travel a long distance and even camp here only to capture a mome nt of the nature wonder. The silver birch turns golden, while the larch is still proudly green. You will find yourself drowned in the intoxicating red of the wild fruits as well as the glamour of flowers in full blown. And your heart will be lingering on the woods as it39。 指導(dǎo)教師聯(lián)系方式： 固定電話： 13956179626 EMail： 注： 2021 年 12 月中旬之前交論文初稿， 2021 年五月中旬論文答辯 指 導(dǎo) 教 師 評(píng) 語(yǔ) ????????????????????? 簽名： 年 月 日 蕪湖職業(yè)技術(shù)學(xué)院畢業(yè)設(shè)計(jì) ?畢業(yè)設(shè)計(jì)任務(wù)完成清單 ?? 說(shuō)明書(shū)： 一 份共 三十三 頁(yè)； 圖 紙：共 一 張， 其中裝配圖 零 張，零件圖 一 張； 電子文檔：文件夾 六 個(gè)； 文 檔 一 個(gè)； 內(nèi) 容： 用三維軟件 Pro/E 對(duì)空調(diào)外殼進(jìn)行建模、模具設(shè)計(jì)以及 NC 加工 蕪湖職業(yè)技術(shù)學(xué)院畢業(yè)設(shè)計(jì) 為你提供優(yōu)秀的畢業(yè)論文參考資料，請(qǐng)您刪除以下內(nèi)容， O(∩_∩)O 謝謝?。?！ 2 Many people have the same mixed feelings when planning a trip during Golden Week.
