question related to year 1987 Authentication process

I have a personal document it signed in Year 1987, it was only stamped by the Chicago consulate and had no stamp of authentication by U.S. Department of State. According to Chinese Embassy's Authentication Process. The Chinese Consulate General is responsible for legalizing notarial documents that have been duly authenticated by the U.S. Department of State over which it hold consular jurisdiction. My question, is this document qualify as an legalized document? I am looking for your advice and thanks for your assistance.
