Dictionary of ancient Chinese in ancient Chinese books.

In fact, the Ancient Chinese Dictionary (Commercial Press 1998) contains these two words, and the interpretation of "Yanwu" is "the same as Yanwu". Relatively speaking. "

Chinese (People's Education Edition, 2003): "The Yanwu is in one room."

Chinese (People's Education Edition, 2000): "Talk in one room." In addition, Yanwu has been lent by Zhonghua Book Company (1959) and Yuelu Book Company (1988). I studied Chinese in 2000, so I usually write "greetings".

In my opinion, both should be correct.
