If the female protagonist's name in an ancient novel was Gao Lengyan, then it might refer to a noble and cold female image. The name could be used to describe an independent, confident, and strong woman, or it could also imply her cold, ruthless, and arrogant attitude. However, it was important to note that the specific plot and background would affect the choice of the female protagonist's name, so the specific situation needed to be analyzed in detail.
