What is the previous line of the poem "Only in Asakusa can the horse's hoof be stopped"?

Spring trip to Qiantang Lake

Bai Juyi

North of Gushan Temple and west of Jia Pavilion

The water surface is initially flat and the clouds are low

< p>A few early orioles are vying for warmth in the trees

Whose new swallows peck at the spring mud

The flowers are gradually becoming more charming

Only in Asakusa can there be no horse hooves

The eastward direction of Favorite Lake is insufficient

The white sand embankment in the shade of green poplar trees
