Which city in China has a hotel with a sundial?

Xi'an Huashan International Hotel.

There is an equatorial sundial at the entrance of the Huashan International Hotel near Xi'an North Street. Both the sundial and the hotel were built nearly seven or eight years ago.

The original meaning of sundial refers to the shadow of the sun. The modern "sundial" refers to a timing instrument that used the shadow of the sun to measure time in ancient times, also known as a "sundial". The principle of a sundial is to use the projection direction of the sun to measure and divide time. It is usually composed of a dial needle (table) and a dial surface (table base with scales). The method of using a sundial to tell time is a major invention of mankind in the field of astronomical timekeeping. This invention has been used by mankind for thousands of years.
