The Ginseng Trail stretches from Group 8 of Wanwanchuan Village in Kuaimamao Town to Bangchui Mountain beside Ying'e'bu Reservoir. Its starting point is the Old Gatherer’s Tomb, namely the tomb of Sun Liang. Nestled amid lush trees and green grass, the tomb faces the Hunjiang River and Lagula River in the front and leans against green hills at the back. It is built of granite.

Carved on a huge recumbent boulder beside the tomb is Sun Liang’s final poem, widely circulated across the Changbai Mountain area: "Born in Laiyang, my surname is Sun,

I crossed the seas to dig for ginseng.

I lost my sworn brother on the way,

I followed the Lagula River upstream to search.

For three days, I ate nothing but a mole cricket,

I would not rest until I found my brother."

The poem reflects the hardships ancient ginseng diggers endured and Sun Liang’s sincere loyalty to his friend. The place was named after the Old Gatherer’s Tomb for over a century, and was renamed Wanwanchuan in 1966. Starting from Sun Liang’s tomb, the trail passes through Kuaimamao Town (the county seat) and Jindou Manchu and Korean Ethnic Township, and ends at Bangchui Mountain by Ying'e'bu Reservoir.

As a key tourism brand of Tonghua County and a featured tourist route of Tonghua City, the Ginseng Trail boasts profound cultural heritage and is accessible all year round. Along the way, tourists can listen to numerous popular legends about ginseng, taste delicious local delicacies, experience distinctive ethnic customs, and enjoy the picturesque scenery of green mountains and clear waters. It is truly a rewarding journey.
