স্মার্ট বাথরুমের আয়না: আয়নাগুলির বিকাশ এবং ইতিহাস

মানুষ প্রাচীন কাল থেকেই স্ব-প্রতিবিম্বিত বাছাই করতে সক্ষম হয়েছে। শুরুতে, জল একটি হিসাবে ব্যবহৃত হতআয়না. From the Yin and Shang Dynasty to the Tang, Song, Yuan, Ming and Qing Dynasties, the আয়না for self-reflecting evolved into a bronze আয়না. The earlier glass আয়নাs in China appeared in the Ming and Qing Dynasties. It was brought from Europe by missionaries who came to China. This European-style glass আয়না has to go through tens of thousands of miles of sea roads and bumps all the way. Taking into account the fragility, the আয়না surface is generally narrow and easy to carry; the আয়না is mostly used for shaving and shaving, and the আয়না surface is only enough to shadow the partial beard.Then, with the passage of time, the silver আয়না used by most of us came into being. With the development of technology, the function of the আয়না is only self-reflection, it is more intelligent and more humane. More functional, such as: anti-fog, watch time, measure temperature, watch TV, etc. The material of the আয়না has also been upgraded from a silver আয়না to an "environmental protection আয়না". This আয়না uses lead-free paint, which is a technical breakthrough of silver আয়নাs. This kind of আয়না is called a lead-free and copper-free আয়না, also known as an "environmental protection আয়না.
