What does it mean to stand at home?

Based on home, it is to solve your own affairs without the influence and interference of external forces. In China, it is very important to stick to the principle of foothold in the domestic market. China is a big country with a population of1400 million, with a vast territory. Everything should proceed from China's national conditions. For example, in grain production, we should base ourselves on the domestic market and ensure basic needs, because China has such a large population that no amount of grain imported can solve the fundamental problem, let alone be controlled by other countries.
