In recent years, the "department-building movement" in domestic business circles has been surging. In the capital market, two or more listed companies with some connection usually constitute what people often say is "a certain department". Delong School, Sweet School, Zhongguang School, Katie School, Tian Fei School, Top School, Nongkai School, Hongyi School, Chaohua School, Jade Bird School, Greencool School, Success School and Minglun School.

However, behind the seemingly endless "system construction movement", there is a more "shocking" "system destruction wave".

According to the survey of New Finance in early 2003, in the past three years, nearly 40 companies have surfaced and more than 200 related listed companies have gone public. After 2003, some departments disappeared and some new departments appeared, such as Seiko Department, Comac Department, Shanghai Stock Exchange Department, Golden Eagle Department and Yintai Department. Regrettably, they only lead the way for three or five years, and some times are even shorter, and the "halo" on their heads is also eclipsed.

Although the "sacrifice" of these "departments" has its own reasons, almost all the words-"broken cash flow" and "broken capital chain" appear in various media reports on them.

Especially since 2005, capital chain rupture has become one of the hottest words in China's capital market. After the collapse of Delong Department due to "cutting meat", there are also "Zhuojing Department" and "Hongyi Department", and the cutting meat of Southern Hi-Tech and Kelon, which are strongly supported by the government, has made the market stunned.
