The goal of this clinical trial is to Improve the quality of life in Hemodialysis patient. The main questions it aims to answer are: * \[Improve the self-compliance of dialysis patients with weight management\] * \[alleviate the volume load of dialysis patients and reduce cardiovascular complications\] Participants will be divided into two groups based on a weight management regimen： Control group: received routine outpatient management. Specific methods: The dialysis doctor registered the information of the patient\'s weight and blood pressure at the end of dialysis, and informed the patient of the purpose, role and importance of weight management. Intervention group: On the basis of routine outpatient management, patients or their family members were subjected to remote follow-up management based on wechat, and the follow-up time was 6 months. Specific methods: Same as the control group, the information of weight and blood pressure of the patients was registered at the end of dialysis, and the purpose, role and importance of weight management were informed to the patients. On this basis, a special wechat signal is set up to add patients or patients\' family members as wechat friends and establish a wechat interaction platform with patients. In the interdialysis period, remind patients to weigh themselves through wechat (the time of each weighing is fixed, preferably consistent with the time of weighing in the hemodialysis center), control the weight gain during the interdialysis period not to exceed 4.5% of dry weight, and inform patients again about the purpose, role and importance of weight management.
