However, there is no scientific evidence that the candle itself will bring yang or any other form of energy. Yang Qi and Yin Qi are concepts in China's traditional philosophy, which have nothing to do with the material world, but more to do with the balance between people's physical and mental state and the environment.
Therefore, it is impossible to scientifically confirm whether the candle is really positive. This view is mainly based on personal beliefs and cultural traditions. If you believe that candles can bring yang, then you can judge according to your own feelings and experiences. If you are skeptical or don't believe this view, then you can choose not to consider its impact.
