Detail steps and code snippets:

Step 1: Create a new PDF document and add a new page to it.

PdfDocument pdf = new PdfDocument();
PdfPageBase page = pdf.Pages.Add();

Step 2: Use PdfTrueTypeFont class and PdfCjkStandardFont class to generate fonts that support simplified and traditional Chinese characters.

PdfTrueTypeFont font = new PdfTrueTypeFont(new Font("Arial Unicode MS", 11f), true);
PdfCjkStandardFont font1 = new PdfCjkStandardFont(PdfCjkFontFamily.MonotypeSungLight, 11f);

Step 3: Use PdfCanvas.DrawString(string s, PdfFontBase font, PdfBrush brush, float x, float y) method and the generated fonts to draw Chinese characters to specified location of the PDF file.

page.Canvas.DrawString("中国", font, PdfBrushes.Red, 50, 50);
page.Canvas.DrawString("中國", font1, PdfBrushes.Red, 50, 70);

Step 4: Save the PDF file to disk.

pdf.SaveToFile("result.pdf");

Run the project and we'll get the following result PDF file:
