Weiping Waits
170km | 2 to 3 Climbs with optional steep | Good Road with a bit of gnarly at the end of the down hill of hill 1 and 2. Try the Clean Race Route for a few added steep sections. The the Easy Clean Reverse for a nice 150km or so and not serious steep parts.
There are a few other loops in there. There are also nice routes south to Qiandao Lake.
