Lin Yongjian as Xi Gengtian and the Mobile Toilet

In Episode 7 of the TV series 'The Story of Xi Gengtian,' Xi Gengtian (played by Lin Yongjian) gets a sudden inspiration while rushing to the toilet due to a pressing need. He converts a tractor into a mobile toilet and starts a manure collection business, becoming a local celebrity and attracting media and commercial attention. Here is a detailed analysis of the specific plot:

1. Event Trigger: A Pressing Need Sparks a Business Idea

On his way to the county seat to buy fish fry, Xi Gengtian urgently needs to use the toilet and discovers that public toilets in the county charge a fee. This detail reflects the inadequacy of rural infrastructure at the time and makes him keenly aware of the potential demand for 'toilet economy.' He realizes that providing convenient mobile toilet services could not only solve farmers' toilet problems but also generate income by collecting manure as organic fertilizer.

2. Action Implementation: Converting a Tractor into a Mobile Toilet

Xi Gengtian borrows money to buy a tractor and modifies it into a simple, movable toilet. The innovations of this approach include:

• Low-cost operation: Utilizing existing agricultural machinery for modification reduces initial investment;
• Resource recycling: Collecting manure to achieve 'turning waste into treasure,' aligning with the concept of sustainable agricultural development;
• Flexibility: The mobile toilet can cover the county seat and surrounding rural areas, breaking through the geographical limitations of fixed toilets.
  Although the design is rudimentary, it meets the needs of rural areas for sanitation facilities and fertilizer at the time.

3. Social Impact: From Celebrity Effect to Business Collaboration

Xi Gengtian's mobile toilet business quickly triggers a chain reaction:

• Media attention: Television interviews make him a 'celebrity,' highlighting the innovative spirit of grassroots farmers;
• Commercial value: A major company from the provincial capital actively seeks collaboration and signs a purchase and sales contract, indicating the market expansion potential of his model;
• Social significance: This plot reflects the exploration of economic opportunities in rural areas during the early stages of reform and opening up, as well as the combination of individual economy and collective needs.

4. Character Portrayal and Thematic Expression

Lin Yongjian's portrayal of Xi Gengtian through this plot showcases the farmer's practical wisdom and risk-taking spirit. He dares to break away from traditional thinking and transforms a daily necessity into a business opportunity, reflecting the TV series' affirmation of individual struggles in the context of rural reform. Meanwhile, the contrast between the 'rustic approach' of the mobile toilet and subsequent business collaborations also implies the inevitability of rural economic transformation towards modernization.

This plot presents a serious theme with humor, aligning with the light-comedy style of the TV series while conveying deep thoughts on innovation, resource utilization, and rural development.
