"Can you learn less?" What does solid mean?

it seems that you can learn less kung fu! I think it means kung fu.

Translation

To the east of Linchuan County, there is a highland that rises slowly and faces a stream, which is called Xincheng. Above the new town, there is a low-lying rectangular pool called Mo Chi of Wang Xizhi. This is described by Xun Bozi, a Southern Song Dynasty man, in Linchuan Ji. Wang Xizhi once admired Zhang Zhi, a calligrapher in the Eastern Han Dynasty. He practiced calligraphy by this pool, and the water in the pool turned black. This is his legacy. Is this really the case?

when Wang Xizhi didn't want to be forced to be an official, he traveled all over the east and went boating on the East China Sea, so as to be quick to concentrate on the scenery. Did he ever rest here when he was wandering around and enjoying himself? Wang Xizhi's calligraphy didn't get better until his later years. It seems that his profound attainments are due to his hard work, not his genius. However, none of the later generations can match Wang Xizhi. I am afraid that their learning skills are not as good as Wang Xizhi's. It seems that learning kung fu can be less! What's more, what about people who want to achieve high moral achievements?

Next to Mo Chi is now the school building of Fuzhou State School. Professor Wang Jun was afraid that Mo Chi's deeds would be lost in oblivion, so he wrote the six Chinese characters "Jin Wang Youjun Mo Chi" hanging between the two pillars in front of the door to mark it, and said to me, "I hope to have a narrative article." I speculate that Wang Jun's mind is not because he loves other people's strengths, even if he is skilled, he won't let it be buried, so even his remains are taken seriously? Or do you want to promote Wang Xizhi's hard work in Linchi to encourage the students here? People have a skill, but they still respect future generations to this extent, not to mention how the fashion and virtue left by benevolent gentlemen will affect future generations!
