Lao Mountain Taoist(崂山道士)

A long time ago, there was a young man called Wang Qi. When he heard that there were many immortals in Lao Mountain, he went there at once. There was a Taoist who still looked young although he was very old. Wang Qi became one of his pupils. During the first month, Wang Qi went to the hills for woods with others every day and listened to the instructions of his teacher patiently. In the second month, he felt that he could not stand the hard and tiring life, but he still waited for the teacher to teach him the magical skills. In the third month, he could not bear the suffering any longer. Upon requests, the Taoist taught Wang Qi the incantations to recite for walking through walls. - Source (cn.hujiang.com)
