Three steps to a printed sheet — all print details here.三步出纸，打印细节都在这。
Type characters / words / poems in the left panel. Line breaks start a new paragraph; punctuation is auto-stripped (except composition & vertical modes). Pinyin / English / Number templates auto-filter Chinese characters so input stays consistent.在左侧输入要练的字、词、古诗或单词。换行表示另起一段，标点会被自动过滤（作文格与竖排除外）。拼音 / 英文 / 数字模板会自动过滤汉字，输入也不会错版。
Polyphones default to the most common reading; click in the "Pinyin" panel to switch, e.g. 了 le / liǎo, 行 xíng / háng.多音字系统默认取最常见读音，可在「拼音校对」里点击切换，例如「了」le / liǎo、「行」xíng / háng。
Click "Print / Save PDF", pick A4, scale 100%, and enable "Background graphics" to match the preview exactly.点击「打印 / 存 PDF」，在打印窗口选择 A4、缩放 100%、勾选「背景图形」，即可得到与预览一致的字帖。
With tracing on, practice cells after the demo show a faint model character; lower opacity to ~15% for a standard copy-practice sheet.打开描红后，示范格后的练习格会显示淡淡的范字；把深浅调到 15% 左右，就是标准的临摹练习纸。
