Zhang Deshun, demanding 180,000 in compensation, colluded with villagers to take the lead in blocking the construction of the village irrigation canal. Project manager Lin Qingyue adhered strictly to principles, preferring to add 170,000 in costs to reroute and build a mountain-encircling canal rather than compromise with unreasonable trouble-makers. When a drought struck, the new canal benefited the farmland of the entire village, except for Zhang Deshun and two other households who missed the chance to connect to the water due to obstructing the project, leaving their crops completely ruined. Having gone through harsh reality checks, the three of them came to their senses, actively apologized, and finally connected to the branch canal, while also voluntarily serving as canal maintenance workers, verifying the simple truth: 'When the canal is clear people's hearts are smooth, and with one heart days prosper.'
