Su Wan kindly funded the construction of a road for the village, but encountered Wang Gang, who took the opportunity to demand compensation. He stubbornly blocked the project, asking for an exorbitant price, and ultimately missed the golden opportunity for a free road. Su Wan helplessly withdrew her funds and left, leaving the dirt road as bumpy and uneven as before. On the day of her son's grand wedding, a torrential rain washed out the dirt road, leaving the wedding cars stuck in the mud unable to move an inch. Guests complained endlessly, and the happy event almost turned into a farce. This painful lesson finally awakened Wang Gang, making him understand that narrow-minded greed is the hardest road to pave. Some roads are built on the ground, while others must be built in the heart.
