The technical chart is clearly outlined, with the upper pressure level like a boulder across, showing significant suppression power, and the bulls' offensive repeatedly thwarted. The bears are gathering strength, and the downward trajectory has become clearly directed, with the trend pattern not to be ignored. In view of this, we should closely follow the market pulse, focus on high points, with Gao Kong as the main, and patiently wait for the flowering of profit-taking in cautiousness and boldness.
