After being brought to the United States by his son Xiaosheng (Wang Bozhao), Lao Zhu (Lang Xiong) did not enjoy a peaceful life. Instead, he encountered many new worries because of the language barrier and many differences in living habits with his writer daughter-in-law Martha (Deb Snyder) (Lao Zhu was not curious about Martha's world. Although Martha was curious about Lao Zhu's world, she did not want to understand it in depth, but felt deeply disgusted after the curiosity). The stubborn Lao Zhu was discouraged (he actually tasted the taste of living under someone else's roof in his son's house!), and ran away from home in anger. An accidental incident made the American media marvel at Lao Zhu's Tai Chi skills. Xiaosheng and Martha also found Lao Zhu after watching the TV news, but Lao Zhu at this time had realized that it was better to be in a miserable situation than to lose his integrity in his later years.
