明永乐时期(1403-1424年)，是明代青花的"黄金时代”，这件杯的核心特征，永乐典型的“压手杯”类小杯(或同风格撇口杯)，口沿外撇、深腹、圈足，胎体“口薄底厚”一一 口沿胎薄、向下渐厚，执于手中有 “压手” 的厚重感，是永乐青花的标志性器型;永乐青花极少署款，仅"压手杯”会在杯心纹饰(如双狮戏球)中暗藏“永乐年制”篆书款，是明代最早的官窑年号款之一。

The Ming Yongle period (1403–1424) is regarded as the "golden age" of Ming underglaze blue porcelain. This cup features core characteristics typical of Yongle-era small cups, such as the iconic "yashou bei" (hand-pressing cup) or similar-style flared-rim cups. It has a flared rim, deep belly, and ring foot, with a "thin-rimmed and thick-bottomed" body — the rim is thin and gradually thickens downward, creating a substantial "hand-pressing" weight when held, a signature form of Yongle underglaze blue porcelain.

Yongle underglaze blue porcelain rarely bears marks; only the "yashou bei" hides a seal-script mark "Yongle Nian Zhi" (Made during the Yongle Reign) within the central motif (e.g., two lions playing with a ball), making it one of the earliest imperial reign marks of the Ming Dynasty.

主题:缠枝莲纹是永乐青花的经典纹饰，以莲花为主体，搭配连绵的缠枝藤蔓。

风格:永乐缠枝莲“疏朗流畅”--莲花造型饱满、缠枝线条柔和，布局均匀不繁密，体现了永乐青花“典雅大气”的审美;

寓意:莲花象征“清廉、纯洁”，缠枝纹寓意“连绵不绝”，组合后代表“清廉永续、吉祥绵长”，是永乐宫廷与民间均推崇的吉祥纹饰。

Theme: the interlocking lotus pattern is a classic motif of Yongle underglaze blue porcelain, featuring lotus flowers as the main subject paired with continuous interlocking tendrils.

Style: the Yongle interlocking lotus pattern is characterized by "spaciousness and fluency" — the lotus flowers are full-shaped, the interlocking tendril lines are soft, and the composition is evenly spaced without being dense. This embodies the "elegance and grandeur" aesthetic of Yongle underglaze blue porcelain.

Meanings: the lotus flower symbolizes "integrity and purity," while the interlocking scroll pattern embodies "endlessness and continuity." Combined, they represent "perpetual integrity and enduring auspiciousness" — an auspicious motif revered both in the Yongle imperial court and among the common people.
