Brief summary: This study was a Phase III multicenter, blinded, and positive active-controlled clinical study to evaluate the efficacy, safety, and immunogenicity of recombinant human albumin(rHA) injection for the treatment of hypoalbuminemia in cirrhotic patients with ascites.

Detailed description: This study was a Phase III multicenter, blinded, and positive active-controlled clinical study to evaluate the efficacy, safety, and immunogenicity of recombinant human albumin(rHA) injection for the treatment of hypoalbuminemia in cirrhotic patients with ascites.After the primary efficacy endpoint ALB reaches the equivalence standard (-2 g/L to 2 g/L, test drug - control drug), a non-inferiority judgment will be made for the key secondary efficacy endpoint of the improvement rate of ascites depth (\> -10%, test drug - control drug). Dosage: 20 g/day once daily for 7 days.

Eligibility criteria: Inclusion Criteria:

* Male or female subjects aged 18-75 years (inclusive）.

* Subjects who were able to understand and comply with the study procedures, voluntarily participated this study, and had signed the informed consent form (ICF).

Exclusion Criteria:

* Subjects with a history of allergies to biological products derived from Escherichia coli, yeast, or Chinese hamster ovary (CHO) cells, or blood products such as HSA.

* Subjects with uncontrolled infections, such as body temperature \> 37.5°C, white blood cell count \> 1.0 × 10\^10/L, or severe abdominal infection, upper respiratory tract infection, lower respiratory tract infection, urinary system infection, etc.).
* Subjects with a history of hepatorenal syndrome (HRS), or serum creatinine (Cr) \> 2 × the upper limit of normal (ULN), or Cr increased by \> 50% during screening period; or presence of urine protein 2+ or more.
* Subjects with other severe underlying conditions that, in the opinion of the investigator, affected the participation in this study, including but not limited to malignancies (exclusion criteria below for liver cancer patients), complicated portal vein thrombosis, non-cirrhotic portal hypertension-related ascites, ischemic heart disease, stroke, chronic obstructive pulmonary disease, and Grade III-IV (NYHA) heart failure, and those with gastrointestinal bleeding who had stopped bleeding for less than 14 days after treatment or failed to stop bleeding after endoscopic variceal ligation.
* Subjects with stage C and D liver cancer (according to the Barcelona liver cancer staging criteria), or hepatocellular carcinoma (HCC) stage A/B requiring chemotherapy, intervention, surgery, or a combination of liver cancer Patients with hepatic venous cancer thrombus;
* transplant subjects
* Female subjects of childbearing age who test positive for serological pregnancy, or female subjects of childbearing age and male subjects who refuse to use contraception during the trial period or within 6 months after the last dose;
* Subjects who had participated in other clinical trials and used the investigational drug within 3 months prior to screening.
* The patient has the following laboratory test abnormalities: (1) Platelets (PLT)\<30x10 \^ 9/L; Hemoglobin (HGB)\<70gL; (2) Alanine aminotransferase (ALT)\>5 × ULN (upper limit of normal); Aspartate aminotransferase (AST)\>5 × ULN; Serum bilirubin (TBIL)\>3 x upper limit of normal (ULN) ; (3) Prothrombin activity was \<40%, and prothrombin time (PT) was longer than 5s; (4) Left ventricular ejection fraction (LVEF) \<50%.
* Individuals who test positive for human immunodeficiency virus (HIV) antibodies; Treponema pallidum specific antibody positive and treponema pallidum non-specific antibody titer positive (unless no intervention is required during the study period assessed by the investigator);
* Other reasons the investigator considered not suitable to participate in the study.
