However,there are still problems such as small scale of individual household,slow technological progress,low level of industrial mechanization and labor saving,and hidden dangers in safe production of sericulture. It is recommended to fully build mulberry gardens and lay a solid foundation for the sericulture industry; implement compound operations to increase the level of income growth; deepen three major innovations,break through the bottlenecks; expand industrial functions,promote integrated development,and accelerate the high quality development of the sericulture industry in Dongtai City.展开更多

The group opened its first enterpriseon China's Mainland--the Fuda Industry Co.Ltd.in 1989 in Xiamen,with an investmentofUS＄ 6 million.The Fuda Company appliesadvanced international techniques andprocesses to design and produce completesets of equipment for making plastic bags,which are paralleled with those made inEurope,the USA and Japan in quality展开更多
