I believe many people would classify this particular development as an "omen" with a "sense of impending doom:"

China is telling families to stock up on food and other daily essentials as bad weather, energy shortages and Covid-19 restrictions threaten to disrupt supplies.

The country's Ministry of Commerce late Monday issued a notice directing local governments to encourage people to stockpile "daily necessities," including vegetables, oils and poultry, in order to "meet the needs of daily life and emergencies."

The agency also urged local authorities to make sure that people have an "adequate supply" of essentials this winter into next spring. And it told those authorities to keep prices stable — a source of anxiety in recent weeks, as the cost of vegetables has surged throughout China because of unusually heavy rainfall that has hurt crops.

Well, that's, um...

To be fair, it is Communist China, which is well-known for its global psy-ops campaigns; it would probably not be beyond the Communist leadership of the country to manufacture the appearance of a crisis in order to effect some sort of political leverage.

Don't trust commies!
