Gelonghui, April 3 | Jianghe Group (601886.SH) said on the investor interactive platform that the company's curtain wall business basically does not involve traditional real estate customers, and since residences hardly use curtain walls, it is not very relevant to the real estate completion logic. However, the curtain wall industry is also seasonal. The first quarter was affected by the Spring Festival holiday. The release of output value was relatively low compared to the next three quarters. The 2-4 quarter or the second half of the year was a period of concentrated output value release.
