姜云涛 (chief executive) discloses dealings in 长春高新 to SSE / SZSE (CSRC). In total, 3 filings cover trades dated from 25 August 2021 to 21 January 2022.

Purchases make up the whole of the open-market record (3 purchases, €949k). A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Since January 2022: 1 purchase and no sales on the market.

In size, the median ticket on the buying side is €344k. 2 out of 3 purchases came within 30 days of a purchase by at least one other insider of the same company. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase. After 3 purchases with a full 90-day history, the hit rate stands at 33% and the median 90-day move at -14.0%. This is a record of the past, not a forecast.

The latest filing, published on 21 January 2022, reports an open-market purchase of €344k in 长春高新. Half of the filings or more reach the SSE / SZSE (CSRC) feed on the day of the trade. The shorter that gap, the sooner other investors can see what insiders have done. This summary is built from SSE / SZSE (CSRC) disclosures alone and does not predict where the share price will go.
