The ancestors of the Li family and the Sun family agreed early on to allow three meters each to build a road. The Sun family broke the agreement and occupied the entire Li family boundary for 30 years, pouring sewage all year round and allowing children to bully the Li family's sister. The Sun family privately occupied the Li family's land to build a road, but instead came to ask for 20,000 yuan in road construction fees. Li Hao tolerated the plan and sent an excavator to block the wedding road on the eve of Sun Qiang's wedding, disrupting the marriage.
