Answer the following question!

    Yongker was a poor man. He lived with her mother. He collected firewood from the forest, and then sold them in the market to fulfill their needs.

    One day, he went to the forest to look for wood, but he could not find any. The day was almost dark, so he looked for a place to sleep. Finally, he found a hut.

    In the morning, an old man suddenly woke him up. The man asked why he slept there. Yongker told him that he was lost when he looked for wood.

    Then, the old man asked him to go to a place near the hut. There were bamboo trees. The old man knew that Yongker was kind, so he gave him great power. Yongker had to use it wisely. Then, the old man took a bamboo and hit Yongker to try the power. Yongker did not feel pain. After giving the power, the man and the bamboo trees disappeared.

    Later, Yongker helped people in need using his power. People named the place where Yongker met the old man as Bulu Pamali. Bulu means 'bamboo' and pamali means 'gone mysteriously'.
