Traveling through time may provide an opportunity for ambitious people or frustrated people full of regrets to change their lives, let themselves be involved in the prosperity and destruction of the country, and continue the great cause of the peerless. You can definitely ask N wives, and at the same time, you don’t have the convenience of asking Baidu about foreign affairs, you don’t have Marlboro and Hongtashan in your mouth, you don’t have Wuliangye and Remy Martin in your cup, you don’t have the sharp weapon of emergency and cool Zippo, I don’t even want to eat more flavorful food. I don’t have Mrs. Le Meiji or Lee Kum Kee... Only after the iron curtain in the torrent of time and space falls, the travelers will realize: how cruel is that world? Nostalgia is worth cherishing. The protagonist Ye Tao is just one of the traversers. As an industrial designer, a person who permeates the quality of life and design concepts to his bones, he has no choice but to lay out the blueprint and make the most of what he can think of. Make the same things again...by the way, add some ingredients.
