Li Han consolidated its operations to its new 6 acres Lu Chu factory on October 1, 1990 to meet increased customer demand and to provide better customer service. The new factory consists of automated facilities with a 24,500 tons storage capacity and is capable of producing 10,000 tons of feed per month with only one shift of 20 plant workers.

Li Han uses a stringent selection process to select its raw materials to manufacture animal feed and organic fertilizers. Li Han also has an extensive internal quality assurance process in place to assure its customers receive the highest quality of products.

Taiwan is moving towards a sophisticated agricultural process that seeks higher yields on less land today. The past use of chemical fertilizer, although successful, has nevertheless been proven that after its prolonged use leaves soil acidized, hardened, and stripped of natural nutrients, which results in poor overall crop quality, crop diseases, pest problems, and flavor loss. Recognizing these harmful effects on the ecological system and human health, Li Han, pioneered what is the now the most recognized brand of Chieng-Chwen Organic Fertilizers.

Most of the fertilizers in the market are made mostly of chemicals or animal excrements, Li Han's organic fertilizers are made of premium imported raw materials such as bone meal, rapeseed meal, alfalfa and wheat bran. Long-term usage of Li Han's organic fertilizers improves soil circulation, protects water resources, minimizes environmental pollution and strengthens crops' endurance to cold, heat, dryness and crop pests, which in turn improves production capacity and crop quality. Furthermore, usage of Chieng-Chwen Brand's odorless, premium organic fertilizers also saves labor costs. Li Han is committed to assist Taiwanese farmers in mitigating the challenges brought about by WTO by helping them harbor a successful transformation.

Li Han cooperates closely with Taiwanese farmers to grow healthy, great tasting, pesticide-free organic produce to capture the organic trend that has exploded in the world. Some of the products Li Han offers are its famous Ba-Lan Organic Oolong and Green Teas, organic honey murcotts, organic grapes, organic longan and organic oranges. Li Han also works with international organic suppliers to offer premium organic goods such as organic clothing to Taiwan consumers.

Li Han is strongly committed to its fundamental principle of meeting customers' needs by providing high quality products at reasonable prices. Li Han considers its employees and its customers as pillar of its stability and success. Many of its employees, some of them with over 30 years of loyalty, consider Li Han as an extension of their "home".

Li Han continues to pioneer revolutionary products and strives to become the top animal feed, organic fertilizers and organic products manufacturer and supplier.
