The Lihua Streak Valley (formerly called Lihuagou) starts from Sanduhe Village in the south and ends at Baduheling Village in the north. There is an 8.1-kilometer span of wetland park along the way. The place got its name for abundant chestnut trees, green mountains and clear waters, and is the key valley-themed leisure tourism destination in Bohai Town, as well as one of the most important ecological valley construction projects in the region.
