1. Differences in food culture: The food culture in Europe and America is different from that in Asian countries. In Europe and America, people tend to eat barbecue, fried chicken, hamburgers and other fast food and western food, rather than traditional Chinese food.

2. Cooking takes time and skill: Compared with easy-to-learn western cooking methods (such as roasting, steaming and boiling), Chinese food usually takes longer to prepare and requires complicated cutting and seasoning skills.

3. Cooking requires high temperature and a lot of oil: Cooking usually requires high temperature and a lot of oil, which may cause the kitchen to become very greasy and easy to cause fire. In Europe and America, people tend to eat healthily, so they don't like to use too much oil.

4. Different ingredients: Due to the differences in natural conditions such as climate and soil, the ingredients in European and American countries are different from those in Asian countries. For example, in China, you can easily find all kinds of fresh vegetables, beans, seafood and other cooking materials, while in Europe and America, people prefer to cook with root vegetables and meat such as potatoes, carrots and onions. These ingredients usually need to be cooked by boiling or stewing, rather than frying at high temperature like Chinese food.

5. Different taste preferences: Due to cultural and historical reasons, Europeans and Americans have different taste preferences for food than Asians. For example, in China, peppers are widely used, and many dishes have a strong spicy flavor; In Europe and America, people prefer light taste, and usually use some simple seasonings to enhance the taste of food, such as salt, pepper and lemon juice. This may also be one of the reasons why cooking is not very popular in European and American countries.

In short, although stir-frying is very common in Asian culture and is considered as a healthy, delicious and convenient cooking method, it is not suitable for all cultures and regions. Every place has its own unique eating habits and taste preferences, and these factors need to be considered when choosing cooking methods. In addition, with the development of globalization and the increase of communication between different cultures, more and more Europeans and Americans began to try Asian dishes, and they gradually accepted the fried cooking methods.
