try (PDDocument document = new PDDocument()) {
PDPage page = new PDPage();
document.addPage(page);
OpenTypeFont otf = new OTFParser().parse("NotoSansSC-Regular.otf");
PDFont font = PDType0Font.load(document, otf, false);
PDPageContentStream contentStream = new PDPageContentStream(document, page);
contentStream.beginText();
contentStream.setFont(font, 12);
contentStream.newLineAtOffset(100, 700);
contentStream.showText("手机号码");
