When leaving Shanghai upon his election into the top leadership, Yu encouraged officials of the metropolis to always maintain "unwavering confidence, pioneering spirit" to build a better future of Shanghai.
Yu's reform campaign began in Yantai, where he initiated one of the country's first housing reform projects as mayor of the coastal city in Shandong Province in the 1980s.
He won the nickname of "mayor of brands" in Qingdao, another coastal city in Shandong. His strategy of brand image building made quite a few brand names in the city, including Haier and Hisense, two electronic home appliances manufactures well known at home and abroad.
