11. All armies prefer high ground to low and sunny places to dark.

凡軍喜高而惡下貴陽而賤陰

Sun Tzu

Armies prefer high ground over low ground because it provides a strategic advantage. From high ground, soldiers can see further and have a better view of the surrounding area. This allows them to spot enemy movements and plan their own tactics more effectively. Additionally, high ground can provide better protection from enemy attacks, as it is harder for the enemy to reach soldiers on higher ground.

Sunny places are also preferred because they provide better visibility. Bright sunlight makes it easier for soldiers to see their surroundings and any potential threats. It also makes it easier for soldiers to communicate and coordinate with one another. In contrast, dark places can make it difficult for soldiers to see and can hinder their ability to effectively carry out their duties.

Businesses prefer open markets that provide equal opportunities for all participants.

In general, businesses prefer open markets that provide equal opportunities for all participants because such markets offer the potential for growth and success. Open markets are characterized by relatively unrestricted competition, which allows businesses to enter and exit the market freely. This freedom to participate in the market provides opportunities for businesses to expand their operations, increase their revenue, and gain a competitive edge over their rivals.

In contrast, markets that are closed or that restrict competition can limit the opportunities available to businesses. Such markets may be dominated by a small number of established players, which can make it difficult for new businesses to enter and succeed. Additionally, markets that do not provide equal opportunities for all participants may be unfair or discriminatory, which can create additional challenges for businesses.

For these reasons, businesses typically prefer open markets that provide equal opportunities for all participants. Such markets allow businesses to compete on a level playing field, which can help them to grow and succeed.
