How to specify 'Chinese' font?

Hi,

I can programatically generate a PDF document with English characters.

I can programatically generate a PDF document containing Japanese characters.

BUT...I cannot get 'CHinese' characters to work.

For Japanese I specify the fonts as follows...

4 0 obj<< /Type /Font /Subtype /Type0 /Name /F1 /BaseFont /MS-Mincho /DescendantFonts [ 5 0 R] /Encoding /90ms-RKSJ-H >>endobj
5 0 obj<< /Type /Font /Subtype /CIDFontType0 /BaseFont /MS-Mincho /FontDescriptor 6 0 R /CIDSystemInfo << /Registry (Adobe) /Ordering (Japan1) /Supplement 2 >> /DW 1000 /W [231 324 500 326 389 500] >>endobj
6 0 obj<< /FontName /MS-Mincho /Descent 0 /FontBBox [ 0 0 1000 1000 ] /CapHeight 1000 /Ascent 1000 /StemV 100 /Flags 4 /ItalicAngle 0 /Type /FontDescriptor >>endobj

...how do I specify 'Chinese'?

Kind regards,

Simon
