Talking about climbing stairs flexibly

Baidu knows that the team will answer for you!

The answer is dragon.

Among the animals represented by the zodiac, only dragons are fictional animals. Since ancient times, people in China have called dragons, phoenixes, unicorns and turtles the four spirits, and considered them the most auspicious animals. The dragon's face is as long as a horse, and its body is like a snake. It has 8/kloc-0 scales on its back and chicken feet on its limbs. You can fly and dive in the air. Mysterious. And the number of scales is 81, which is more meaningful. Dragons are really pampered. Dragons, of course. Take it!
