菇凉满天下都是好菇凉
[gū liáng măn tiān xià dōu shì hăo gū liáng]
'Girls All Over the World Are Good Girls,' indicates appreciation for all girls in the world, emphasizing every girl deserves kindness. In Chinese, 姑凉 (girls) has a different pronunciation than 蘑菇凉 (fungus cool) but it seems like using pun here as a joke or to add a whimsical flavor.
