Hello Henry,
丛 is the simplified version of the character 叢, which means a lot of something existing together. The original character for dancong can be either 單欉 or 單樅. 欉 and 樅 are old variations of the same word. There are a number of old Chinese characters like this. Both of these two variations are 枞 when written in the simplified form.
In the current condition in China, old famous people are often asked to lend their names for various applications for a fee, or a favour. In some situation it is hard to refuse because the request can be from someone with other influence. It is a sad social reality there. I shall photograph the real book that Mr Huang himself wrote and post it on Facebook in a day or two, such that you know what the real stuff looks like.
