Inclusion Criteria: 1. 35 ≤ Age \< 80 years. 2. Regularly attend the clinic for hypertension treatment during the study period, without plans of traveling during the study period. 3. Diagnosed with hypertension, with SBP ≥140mmHg at screening. 4. Currently taking 0 or 2 classes of antihypertensive medications (A/C/D), with or without concurrent use of class B. 5. Willing to participate in the trial and capable of providing written informed consent. Exclusion Criteria: 1. Physician-diagnosed or suspected secondary hypertension (e.g., hypertension caused by renal disease, renal artery stenosis, aortic stenosis, primary aldosteronism, pheochromocytoma/paraganglioma, Cushing's syndrome, thyroid dysfunction, intracranial disease, drug-induced, or rare monogenic genetic disease). 2. SBP ≥180mmHg and/or DBP ≥110mmHg at the screening visit. 3. Suspected or diagnosed white coat hypertension. 4. History of coronary heart disease. 5. History of heart failure. 6. Intolerance to 2 or more classes of A, C,D antihypertensive medications. 7. Currently taking antihypertensive medications other than class A,B,C and D. 8. Diagnosed chronic kidney disease, estimating Glomerular Filtration Rate (eGFR)\< 60 ml/min·1.73m2, or receiving dialysis. 9. Serious medical conditions (e.g., malignant cancer and hepatic dysfunction) 10. Currently in an acute episode of disease (e.g, new-onset cardiovascular and cerebrovascular disease occurred within 3 months). 11. Cognitive or communicative disorders. 12. Currently pregnant or breastfeeding or planning a pregnant or breastfeeding during the study. 13. Reluctant to take antihypertensive medications or have poor compliance with previous treatment. 14.
