During the Qing Dynasty and the Republic of China, the Shantou porcelain industry reached its peak. The folk ceramic utensils such as bowls, pots, pots and pots that were burned by the "Shantou Kiln" were simple and durable, and the marketing was more and more famous. Up to now, there are still more than 30 ancient kiln and 75 ancient dwellings in the site of Shantou Kiln.

The "Xijing Miscellanies" describes the fruit tree varieties of Shanglinyuan: "The group of ministers and distant fruits are dedicated to fruit trees... pear ten... jujube seven... Lisi four... peach ten... Li fifteen... 柰 three... plum Seven...Apricot II", which also records "... 柰 three, white peony, purple 柰 (flower purple), green 柰 (flower green)", that is, small apple or cotton apple.
