Located in Shanghai’s Chongming District, the largest alpaca base in East China ushered in a big day for the animals, for they will have their wool sheared ahead of the summer, and it is also a day of harvest for the alpaca farmers. On Sunday morning, the shearers waiting in the designated area started to shear the wool of the alpacas in the Wild Wide World alpaca farm.Alpaca wool is the best coat for alpacas in winter, but since alpaca wool does not fall off naturally, human intervention is necessary. Before the arrival of summer, shearers will shear the wool for alpacas. After that, the wool will be divided into different packages. Wang Xiong, staff member of Wild Wide World said that the wool on the alpaca's back is the best, which will be packed separately. After the shearing, it is important not to let the alpacas catch a cold, now that they no longer have the wool ‘coat’ to keep them warm, Wang said.
