Professor LAN is actually a young woman?

What came into view was a pair of slender Jade-like hands!

In the background of the red sandalwood table, two slender white hands were gently placed on the edge of the table. The pair of Jade-like hands were white and slender, as white as the root of a scallion, soft and moist, and a pen was held between the fingers.

"Will this do?" A clear voice was heard.

This voice was as clear as a stream in an empty Valley, melodious and slightly pleasant to the ears. It was a very young female voice!

The entire lecture hall fell into silence.

They looked at each other in silence and only reacted after a long time. They discussed the current situation in a low voice ...

"This should be one of professor Lan's young female assistants, right?"

it should be. It can't be professor LAN. If she was a young woman, I would have pulled her head off and kicked it like a ball!
