Costco's first Shanghai outlet opened on Tuesday, drawing so many customers that the company had to enforce a crowd limit just two and a half hours after it opened.
Roads in the vicinity were also jammed due to the number of people flocking to the store.
According to Costco, more than 120,000 people have signed up for its membership since registration started on July 1.
Located in Minhang district, the Shanghai outlet occupies about 14,000 square meters and has 1,200 indoor and outdoor parking spaces.
