+英秀、思賢、一心、向華四人打麻雀，開局英秀坐東家，一心坐南家，向華坐西家，思賢坐北家。這個四人麻將團每周例行聚在一起，分享歡笑、挑戰智慧，維持著多年的友情。
+
+這一天，他們在一心的家中開始了一場激烈的麻將對局。牌局進行得如火如荼，每個人都專注計算牌面，嘗試提高自己的手牌實力。
+
+房間內的氛圍十分融洽，除了麻將牌桌上的熱鬧，還有一盆盆綠植為房間增添了生機。窗外陽光灑落在桌上，映照著牌面的精彩和對局者的笑容。
+
+在一個關鍵時刻，思賢的手牌看似雜亂無章，但他突然宣佈：「自摸十三么！」
+
+這句話瞬間引起了其他三位朋友的驚訝。在麻將中，胡了十三么是極難的壯舉，要求一位玩家贏取所有的牌，包括每一種花色的一到九和字牌。這是一個極為難得的事件。
+
+思賢展示了他的牌，確實是一副完美的牌型，包括了一萬、九萬、一索、九索、一筒、九筒、東、南、西、北、白、發、中。他獲得了壯舉的勝利，贏得了整個牌局。客廳內爆發出驚嘆聲和掌聲，四位朋友都感到非常振奮。
+
+這場牌局成為了他們友誼中的一個傳奇，他們將永遠記住思賢的壯舉。雖然勝負只是一場遊戲，但這個時刻對他們來說意義非凡。當他們繼續享受著遊戲和友誼時，他們知道這個回憶將伴隨著他們一生。而那盆綠植，也見證著他們的歡笑和友情，在陽光下繼續茁壯生長。

+## Description (en)
+
+Amy, Barron, Christina, and Donald are playing bridge. Amy and Christina are seated at East-West, and the tension in the room is palpable. After the last hand, where Donald and Barron narrowly claimed victory, the competitive spirit among the four friends was running high.
+
+As they dealt the cards for the next hand, Amy found herself with an extraordinary hand—nearly all the high cards and an abundance of aces and kings. Her eyes sparkled with excitement as she considered her options.
+
+The bidding phase began with Donald, the dealer, and he started with a conservative one club bid. Barron, his partner, bid one heart. Amy, however, couldn't contain her enthusiasm. She saw the potential for a grand slam, an ambitious contract where all 13 tricks would need to be taken. Without hesitation, she boldly declared, "Seven No-Trump."
+
+A hushed silence fell over the table as Christina, Barron, and Donald exchanged incredulous glances. A bid of seven no-trump was one of the highest bids in bridge, and it signified utmost confidence in one's hand. It was a gamble, but Amy was known for her audacious plays and her penchant for seizing the moment.
+
+Christina, with her East-West partner's bold bid, decided to support Amy's declaration by bidding eight clubs, effectively ending the bidding with a contract of seven no-trump.
+
+The room was filled with anticipation as Barron led the first card, and the game was underway. Amy, the declarer, played with precision and confidence, making every move count. Her East-West partnership was in for an exhilarating ride, and they knew they had to work together flawlessly to fulfill such a high-stakes contract.
+
+As the tricks unfolded, it became apparent that Amy's hand was indeed exceptional. She carefully navigated each play, and the room buzzed with excitement as they approached the final trick. It all came down to the last card.
+
+However, fate can be unpredictable, even in the skilled hands of a bridge player like Amy. Despite her valiant effort, she lost the final trick. The room fell into stunned silence as the reality of their narrow defeat sank in.
+
+Donald and Barron, their North-South opponents, had managed to outmaneuver Amy and Christina in the end. Despite Amy's audacious bid and her skillful play, the contract was not fulfilled.
+
+But in the world of bridge, wins and losses are just part of the game. The four friends, despite the ups and downs of the hand, knew that the thrill of the competition and the camaraderie they shared were what truly mattered. With a smile, they shuffled the cards for the next hand, ready for whatever challenges the game would bring their way.
