Personally, Fujita is the best elevator brand. Seen from the world, Otis, Toshiba, KONE, Mitsubishi, Fujita, Schindler, Thyssen and Hitachi are the earliest joint ventures in China, and Otis is the world's largest brand. Tianjin Otis is just one of his many joint-stock companies, and Shanghai Mitsubishi is not the original trademark. At present, the biggest domestic sales are Shanghai Mitsubishi, Guangzhou Hitachi and Xizi Otis.
