"How terrifying is it for China to enter a state of first-level combat readiness?"

When China enters a state of first-level combat readiness, it typically signifies that the country is facing an unprecedented security challenge. All military forces are mobilized, from ground troops to the navy and air force, all ready to engage in combat at a moment's notice. Strategic weapon systems are activated, and military bases and key facilities are reinforced for defense to ensure national security is not compromised. Concurrently, civil defense measures are intensified to protect civilians and infrastructure from potential attacks. The declaration of such a state is usually accompanied by an atmosphere of tension and concern for possible conflicts, but it is also an important signal of the nation's determination and readiness to protect its sovereignty and the safety of its people.
