Personally, I think that the evaluation is easy to select topics, with many materials and practices, which not only covers a wide range, but also has certain practical significance. For example, Professor Zhao Banghong, Dean of the School of Economics and Business of Hebei Agricultural University, and Professor Wei Jinghong, Director of the Institute of Asset Appraisal of Hebei Agricultural University, have published many valuable papers in this regard, which have been welcomed by the asset appraisal industry and benefited the appraisal industry a lot.
