In 1892, French missionary father Tian Daneng preached in Dali, Yunnan Province, China. In order to drink coffee, he taught local villagers to grow and drink coffee. Up to now, coffee has been planted in Yunnan Province of China for more than 100 years, with an area of 120000 mu. Most of the varieties planted in Yunnan are ccatimor, with an altitude of 1000-1500m, The coffee produced in Yunnan has a balanced taste, rich nut and citrus flavor, some of which are very sweet, with obvious taste of chocolate, toffee and maple sugar. It is one of the high-quality coffee producing areas. Our coffee is produced at the junction of Puer and Burma - the Myitkyina original jungle beans at 1500-1750, with a rich flavor, high aroma and high sweetness. The 2019 international coffee cup Masters Tournament (China finals) is sponsored by beans.

Mixed fish and crab ditch has high benefits
According to the natural habitat and growth habits of crabs, integrating fish and crab polyculture in ditches is an effective strategy to enhance the economic returns of crab farming. This method not only maximizes resource utilization but also promotes a more sustainable and balanced ecosystem.
1. **River Ditch Conditions**: To ensure a suitable environment for crabs, it's essential to select clean, unpolluted river channels with an average water depth of about 1 to 2 meters. The ideal soil type is clay or sandy loam, as it offers good aeration and supports the growth of aquatic vegetation and benthic organisms. The silt layer should not exceed 0.2 meters to prevent poor water quality and maintain healthy conditions for the crabs.
2. **Stocking and Feeding**: Typically, young crabs are purchased from hatcheries between April and May each year. These crabs are usually around 1 kg per 2000 individuals, and stocking density is approximately 150 to 300 crabs per mu of water surface. This ensures sufficient space for growth while avoiding overcrowding.
3. **Feeding and Water Management**: In most cases, the river ditch provides enough natural food sources such as aquatic plants and benthic animals, eliminating the need for artificial feeding. The large surface area and low stocking density help maintain adequate dissolved oxygen levels. The water pH should be kept between 7 and 9. If the pH drops below this range, quicklime can be applied to prevent shell softening and reduce mortality. Regular inspections of the ditch’s boundaries are crucial—ensuring that nets and barriers are secure to prevent crabs from escaping. Adding additional layers of mesh or barriers can further improve containment. The surface netting must also be intact to prevent crabs from climbing out.
4. **Harvesting Crabs**: The best time to harvest crabs is typically after mid-September, when their gonads mature and they begin migrating. Due to the open nature of river ditches, it's important to increase fishing efforts during this period. Fishermen commonly use fixed nets like shrimp traps or cage nets to catch crabs effectively. This timing helps maximize yield and ensures the crabs are at their peak market value.
