"Boiling ink" means boiling ink. In ancient times, when writing calligraphy and painting with ink, it was necessary to grind the ink first, so there were sayings of "grinding ink" and "soaking pen". And "gaining momentum" means accumulating strength and preparing for the next action.
Therefore, the term "boiling ink and gaining momentum" can be understood as that in modern painting or calligraphy, by means of boiling ink and grinding ink, we lay a solid foundation for the next step of creation, and at the same time accumulate strength to create more excellent works.
