Actually, according to the general thinking of the people in the Great Tang, many things are passed on to men and not to women. It makes sense for the Lin Clan Leader to act this way within the context of the times.
But Lin Wanwan, after all, comes from the modern era. She can travel back and forth; she didn't just come to the Great Tang and can't return to the modern world.
Therefore, in her thinking, Lin Wanwan has never been assimilated by the natives of the Great Tang. She does not accept the preference of men over women among her clan!
Since she could travel through time, Lin Wanwan started looking up time travel novels and TV shows online. She couldn't understand why some women who traveled back in time would immediately submit to the ways of the past, adhering to outdated concepts even more than ancient women. Isn't this a huge step backwards in thinking?!
