No Guanxi? No sex information?

Signs posted everywhere at the hospital said the ultrasound techs could not tell us the baby's sex. Looking at the images on the ultrasonic monitor I could not tell. They said there was a nose but it was not apparent to me that it was a nose. I should have spent a week on the Internet practicing ultrasound interpretation.

I was told I should have also slipped them a 100 rmb note.

I have a salon class about Guanxi tonight. I will ask the students if guanxi could have helped.
