ushed a wheelbarrow and peddled the food from street to street〓. He later rented a room in the Erduoyan hutong, a narrow alley. It's thu〓s widely known as the Erduoyan fried cake. Jianbing, or fried crepe topp〓ed with egg and garnish, is a Chinese snack that has seen international f〓ame in the US recently. New York-born Brian Goldberg opened his "Mr. Bing〓" kiosk out of his personal fondness of the Chinese food, which became an〓 instant hit among New Yorkers. A tasty and crispy jianbing is made by p〓ouring batter (made of rice or beans) onto a circular hotplate. After car〓efully spreading the batter with a spatula, an egg is cracked on top. Gre〓en onions, a crispy cracker and any other ingredients that the consumers 〓like are added before the snack is folded into a tidy pocket.A laboratory worker in full biohazard gear is patrolling rows of rainbow〓 colored LED-lit shelves. The shelves stand about 2 meters and have six〓 levels, each containing trays of lettuce saplings bathing underneath t〓he light, and the room is illuminated in a psychedelic pink. A labor〓atory worker in biohazard gear checks the growth of lettuce in the vert〓ical farm in Anxi, Fujian province. ZHAN ZHUO / FOR CHINA DAILY This i〓s no scene from a science fiction movie, but a common sight for scienti〓sts at a plant factory in Anxi, Fujian province, which covers 1 hectare〓 and is the largest vertical farming complex in the world. The second-l〓argest is a 0.64 hectare farm in Newark, New Jersey. Vertical farming 〓is the practice of growing vegetables and fruits in vertically stacked 〓layers of hydroponic solutions in a controlled, indoor environment. It 〓does not require soil, sun or pesticides, and uses far less water and f〓ertilizer than conventional farms. However, the farm's high-energy cos〓t has greatly limited its scale and profitability. In recent years, Chi〓nese scientists at the Anxi plant factory have mitigated the issue by i〓nventing energy efficient LEDs and recyclable hydroponic solutions, as 〓well as new energy-conserving methods to maximize a plant's growth pote〓ntial. San'an Sino-Science, the company behind the project, says these〓 new metho
