As for opening a store in your hometown, it depends on the market demand in your area and your own skill level. If you have mastered sufficient Western pastry making skills and there is similar local market demand, then you can consider opening a Western pastry shop in your hometown. However, you need to consider factors such as market saturation, intensity of competition, store rent, and operating costs.

The most important thing is that choosing to study Western pastry or return to your hometown to open a shop is a personal decision that needs to take into account your own interests, skills and goals. You can make the best choice by consulting professionals, understanding market needs, and experimenting with baking.
