Nice climb. Is your heart rate working 16 is a bit low. Just off Panshan road in Liantang is another entrance which avoids the long walk in fairy lake. Be sure to take plenty of water on hot days and the time will increase quite a bit. Another entrance is wangtong road in Wutong village itself goes up though the forest.
Best way to find routes is Google earth and follow the pictures.
My personal best is 2 times in one week and 6 times yang tai shan. 5000m
