This is a randomized, double-blinded, placebo-controlled, multi-center Clinical Trial. Patients with no tumor lesions 21 days after resection of hepatocellular carcinoma will be randomized in a 1:1 ratio to 1 of the 2 treatment groups：6mg/d Tyroserleutide (injection), or placebo

• The first stage includes evaluation of subjects, to assess the inclusion criteria and exclusion criteria, based on the patients' preoperative imaging results, including tumor size, tumor characteristics, etc.
• In the second stage, subjects will return to the hospital 21 days following the baseline examination.The investigator will determine whether the subject satisfies all inclusion/exclusion criteria. If all requirements are satisfied, then randomization will occur 21 days after surgery
• The day of randomization will be defined as Day 0. Randomized subjects will return to the hospital and begin cycle 1 on the day of randomization (Day 0). and the relevant laboratory tests will be performed within 3 days after the end the study drug infusion.
• Cycles will occur as follows: cycles 2, 3, 4, 5, and n will begin on days 42±3, 70±3, 98±3, 126±3, and 14+28（n-1)± 3, respectively.
• Based therapeutic drugs are Gan Fu Le
• the participant will receive medical inspection so as to observe and ensure drug safety.
