What is a "riding gate"?

The new Princess Pearl broke the "riding gate" and the beautiful lines became "yellow jokes"

The two men were bumping on horseback, and Erkang made a deep confession to Wei Zi: "I will always hold you to the horizon." Wei Zi replied excitedly: "I feel excited, scared, excited, happy and happy now, but I'm worried that the swallow will have another situation." Erkang comforted: "Don't think about that, just enjoy this moment. This is a once-in-a-lifetime opportunity. " Later, when Erkang made a deep confession to Wei Zi, he said, "The last time I rode with you in my arms like this, it was in the faint valley, and I didn't fly like today. I like you so much. " Wei Zi giggled and replied shyly, "Me too." Er Kang said that he didn't hear you clearly, and then Wei Zi shouted like a small cosmic explosion: "Me too, me too, me too. I have as much as you! No, no, I have more than you. " In the face of such a disgusting confession, Erkang drawled and raised his voice and retorted, "You can't be more than me, because I'm full!" Unexpectedly, Wei Zi's final answer was even more shocking: "You are full, then I will overflow, hahaha!"
