Prostrators reach out in the late afternoon noon toward the front of the Jokhang Temple. Behind the prostrators is an enclosure which contains a willow tree said to be planted by King Songtsen Gampo's Chinese wife, Princess Wen Cheng. To the far right is a 3 metre high stone stele, which carries a bilingual inscription of the Tibetan-Chinese agreement of 821 between the Tibetan king, Tri Ralpchen, and the Chinese emperor, Wen Wu Hsiao-te Wang-ti.
