Yin Collection, Upper Volume Radical: Roof (mián) 宸 Kangxi Strokes: 10 Page 287, Entry 02 Pronounced chén. According to the Explaining Graphs and Analyzing Characters (Shuowen Jiezi), it refers to the eaves of a house. Jia Kui states: It is the deepest part of a chamber. Later generations referred to the place where the emperor resides as chen. The Expanded Rhymes (Zengyun) states: The emperor resides in the North Chen Palace, which is why the character form is composed of the radical for roof and the character for chen. It is also called Fengchen. The place where the emperor resides is tall and vast; only large maple trees are suitable for its construction. Discourses of the States (Yueyu) states: If you do not forget the Zhou royal house and protect our small state, it is my wish. The Correct Character Guide (Zhengzitong) states: It was originally written as chen. According to the Six Scripts Origins (Liushugu), it is also written as zhen. Citing the commentary on Yang Xiong's Rhapsody, Fu Qian says: Yang refers to the center, and zhen refers to the eaves. Note: The character chen draws its meaning from the North Star. Contemporary people speak of the chen pole, which is different from speaking of eaves in a general sense. Combining chen and zhen as the same character is incorrect.
