Traditional

Don't take the change in the dressing of dan-dan noodle too lightly. There are in general two opposing opinions:

1. We should stick to the traditional or original preparation.
2. It doesn't matter - we just want something that taste good.

It is easy to see following the first suggestion would put an end to any possible advance and improvement. The young and energetic generation would therefore agree with the second. Nonetheless, if we follow the latter principle blindly and encounter a restaurant that serves a small bowel of thin al dente type of noodle in a clear soup, topped with shrimp won-ton, and calls it dan-dan noodle, you would be somewhat disappointed however good the thing is.

And life is the eternal difficulty of deciding which alteration means an improvement (in the case of dan-dan noodle, for example, the use of chopped peanut to replace sesame paste and minced port), while another small adjustment could not be accepted because it takes away the soul of the original version.

PS. Of course many great leaders are very much familiar with the creative use of language and would call won-ton noodle the real dan-dan, slavery the real freedom, dictatorship the real democracy, et cetera. That's another story.
