Are there any poems dedicated to tea oil in ancient times?

Never heard of ancient. There are modern ones.

Three Songs of Tea and Oil Capital

Ma Xiaoquan

tea-oil tree

Having children hides a big difference,

The appearance and life of farmers are the same.

Endure thousands of years of suffering,

Laugh at today's glory.

Camellia oleifera flower

Beauty is spotless, flowers are gorgeous,

The moon looks clearer after the frost rhyme.

Brew a handful of honey in your heart,

Pay for planting all over the world.

Tea seed oil

Color like gold, smell like cinnamon,

A thousand blows reveal the true colors.

Medicine for beautifying, eliminating diseases and prolonging life,

Born in the eastern part of Shanhaijing.
