According to the interpretation of authoritative dictionaries such as Modern Chinese Dictionary and Chinese Ci Hai, the pronunciation of mushrooms is "mógu", in which "gu" is pronounced softly. This means that in pronunciation, the pronunciation of "Gu" is very slight and almost inaudible. So the correct pronunciation of mushrooms should be "mó[ softly]".

Chinese light tone is a unique phonetic phenomenon, which is different from other languages. Light tone does not refer to the vibration of air flowing through vocal cords, but refers to the state of vocal organs such as tongue and throat. In Chinese, some syllables of some words can be pronounced softly, such as "cursing" in "cursing [mà] people".
