Despite the five years' study in Nalanda Temple, Xuanzang still had questions and he took on the hard journey of study tour alone. On the hot Indian Continent, there were more than 70 kingdoms with varied customs. Passing the Devas Bodhisattva Shrines full of legends and the Lion Kingdom, Xuanzang encountered the man-eater in the jungle of Southern India and accidentally strayed into Ajanta Caves lost for nearly 1000 years, where the eminent monks and masters studied on sutras 200 years after the Buddha's death. Xuanzang got popular throughout India and he was persuaded by Nalanda Temple and Siladitya to stay and had to face numerous unexpected sutra debating, which became the biggest obstacle for his return to the east. Xuanzang's journey to the west = 19 years + 56 kingdoms + 110 cities + 1335 rolls of sutras + 50000 miles. The rising Tang Dynasty, the Turkic people on horseback, the mysterious Central Asia, and India where multiple thoughts collided... All of these were presented in the hard journey of the lonely pilgrim Xuanzang who accomplished the great adventure in the history of human trek hard to exceed.
