Brief summary: 1. Explore the effect of Babaodan Capsule on the serum total bilirubin level of primary biliary cholangitis patients with elevated total serum bilirubin;
2. To observe the positive intervention effect of Babaodan Capsule on the clinical symptoms of primary biliary cholangitis patients with elevated total bilirubin.

Detailed description: 1. Primary objective: to investigate the effect of Baobao Dan capsule on serum total bilirubin levels in patients with primary biliary cholangitis with elevated total serum bilirubin.
2. Secondary objective: to observe the effects of Babaodan Capsule on the following aspects in patients with primary biliary cholangitis with elevated total bilirubin:
