In 2007, I had seen a documentary about cow's life, I decided not to eat milk products since the next day. In the case of permission, I would say to people around me, but my limited capability is little helpful to cattle. In 2011, I met a soymilk maker, but it can only be seen as a puree machine of soymilk residue. Not a substitute for milk. Cannot help cattle. By the end of 2014, I met Yao, he designed the filtering approach, and I studied the better boiling mode. We had made soymilk that is better than milk. We named this plan SECOND MOTHER, and hope to promote it globally, like the second mother, to take care of human beings. It can also solve the difficult situation of cattle, and the adverse effects of milk on humans and the environment. Therefore, if it is slightly modified on the basis of the current product, good residue-free soymilk can be made to substitute milk, and save cow and the planet.
