Food security is the greatest concern of a country. In 2023, we overcame multiple adverse effects such as severe natural disasters, and achieved a new historical high in grain production. Grain production achieved "20 consecutive harvests" and remained above 1.3 trillion kilograms for 9 consecutive years. Always prioritizing the protection of national food security, insisting on relying on our own efforts to stabilize China's rice bowl, ensuring sufficient production and supply in daily life, and being able to withstand and rely on extreme situations, is a powerful proof of adhering to the bottom line thinking. We must not only strengthen our strategic confidence and maintain our belief in victory, but also enhance our awareness of potential risks, adhere to bottom line thinking, and be prepared to withstand major tests of wind, waves, and even storms. Practice has shown that adhering to bottom line thinking and enhancing awareness of risks and challenges are important ideological, working, and leadership methods for our party to overcome risks and challenges, and continuously move from victory to victory.

Various "black swan" and "gray rhinoceros" events may occur at any time. Predicting risks is a prerequisite for risk prevention, and grasping the direction of risks is the key to seeking strategic initiative.

To deal with various potential risks and challenges, it is necessary to have a clear understanding, implement targeted strategies, and accurately dismantle bombs, effectively controlling the situation and resolving crises. We must always maintain a readiness posture with an arrow on the string, see and mitigate various risks before they occur, resolutely prevent the uncontrolled spread of various risks, and resolutely prevent systemic risks. Bottom line thinking is a dialectical materialism, which is an organic unity of "guarding" and "doing". We must not only maintain the bottom line of avoiding systemic risks, but also actively act in identifying and responding to changes, playing a good first mover game and taking the initiative.
