The word "romance" has always been inconclusive, and this sentence is equivalent to the personal opinion of Otani Zhenshan.
The meaning of romantic includes bohemian, not sticking to ethical codes, and celebrities in Wei and Jin dynasties fully meet this requirement. As for Tang poetry ... Personally, I always feel that Li Bai's poems are fantastic and magnificent, heroic and vigorous, and the romance is really different from that of Wang Wei in the period, or even worse than that of Li Shangyin in the late Tang Dynasty-probably because he didn't let go of his fame, and of course there is no difference between the two.
