Which hotel has a square sign?

Vienna Hotel was established in 1993. As a domestic business hotel chain, we adhere to the brand positioning of "sleeping AIDS as the core". At present, Vienna has six sub-brands, more than 500 branches, more than 60,000 rooms and nearly 50 million registered members in 80 large and medium-sized cities in China. Now it is developing at the rate of adding 100-200 branches every year.
