Exterior decoration introduction: The guest house is magnificent and about 30 meters high. It is based on a yellow exterior wall with a thickness of more than 60 centimeters, partially decorated with granite stones, and with beautiful patterns carved on the top, which is simple yet exquisite. The roof paved with beige tube tiles, blue fish scale tiles and green ox tongue tiles makes the building more exquisite and unique. The guest house has a gorgeous appearance and elegant shape. It is still at the forefront of single villa buildings in my country. It can be said to be a unique flower in German architecture.
