A collector had put this bag of Liu Bao tea up for sale last month in Malaysia and I had an opportunity to sample this tea.
This tea is the Ipoh Leong Swee Sang Liu Bao. It came packed, all 40kg, in a thick white bag. The available literature was that this tea was exported through Hong Kong to Malaysia in the 80s. Such Liu Bao tea in the 80s was a popular tea among the Chinese tin mining community in Ipoh from the 30s to the early 80s when the tin mines was depleted. Note the big pink neifei with the Chinese 'fu' character.
This tea has a nice medicinal aroma and taste in the initial infusions. Good for more than a dozen infusions, this tea now is expensive and highly sought after.
