a black and white photo of two tall buildings

I went to the DJI headquarters one more time, and I really liked the architectural style, which is called Brutalism, according to a friend of mine who studied architecture. The building on the left is T2, the research and development center, the level of confidentiality is very high, even DJI employees need layers of security checks to enter. The building on the right is T1, which is used for DJI's general office purpose and is open to visitors on weekends.
