Pinyin/Asthma

See also Asthma is a long-term disease with difficult breathing and panting. It happens repeatedly, and its severity and frequency are different from person to person. When an asthma happens, the inside of the air tubes swells, causing the airways to narrow and breathing difficulty. Xiāochuǎn shì yǒu hūxī kùnnán hé chuǎnqì de mànxìngbìng.
