In the 1980s, the manager of Hong Kong's Lei Garden Restaurant felt that the names of the dishes on the menu were too rustic and did not match the temperament of the upscale restaurant. In order to make the restaurant dish name to attract diners, fashionable and distinctive. So, the manager racked his brains to come up with names for the restaurant's dishes.

One of the desserts is called Mango Sago Dew, which is a popular summer candy sold on the streets of Hong Kong. But the manager felt that the name "Mango Sago Dew" was too cheesy for a "street food" kind of name! The manager decided to change the name to something more elegant.

Manager in order to change the name is racking his brains, suddenly the manager saw a story: said in ancient times, a village in Guangdong suffered a once-in-a-century high temperature and drought, the heat wave rolling, the river is dry, there is no water to drink, the villagers are thirsty and heatstroke, in critical condition. At this time, Guanyin, the Goddess of Mercy, passed by this village and saw that the villagers were about to die of thirst, he immediately used the willow branch in his hand to take out the nectar water in the vase and sprinkled it on the sky of the village, and the sky instantly rained down, saving the villagers of the drought-stricken area.

This allusion to the manager's heart, mango sago dessert is a dessert to quench the summer heat, is reflecting the Goddess of Mercy Yangzhi Ganluo for the villagers to quench the summer heat of the allusion to the mango sago dessert, so the mango sago dessert was renamed: Yangzhi Ganluo.
