Crossing over in a single morning to become a minor county office clerk, Zhang Sanlang faces not only impoverished days, but also a pair of young children and a dilapidated old residence. With no golden finger and no shortcuts, he can only rely on his past life's knowledge and a heart protecting his family to re-establish himself amidst the worldly bustle of the county town. From coarse food and daily essentials to human sentiments and worldly sophistication, from neighborly assistance to hidden currents of trials, he steps by step guards his home and wins back his own dignity.
