Names have a great impact on all aspects of a child's life, so you should be cautious. The most authentic name in Mudanjiang is Mr. Zhou Yinchan, who has now moved to No. 420 Xisan Road (opposite the maternity hospital). Searching for the word "Zhou Yinchan" on the Internet, there is a video of Teacher Zhou teaching. Teacher Zhou is the teacher in the I Ching lecture hall downstairs of Lao Guanghui. Hope it will be adopted.
