This study is a traditional Chinese medicine cohort for interstitial lung disease（ILD） in China, including at least 5000 patients with ILD and followed up for at least 5 years. The aim is to focus on the demographic characteristics, clinical features, disease occurrence and development characteristics, TCM syndrome evolution patterns, and clinical efficacy of TCM treatment for ILD in the real world.
Patients who meet the diagnosis of ILD;
Age≥18 years old;
Ability to provide independent informed consent.

Interstitial lung disease (ILD) is a group of lung diseases characterized by inflammation and/or fibrosis of the lung parenchyma, often accompanied by progressive respiratory distress, which may ultimately lead to end-stage respiratory failure.
Cohort
Prospective
Not listed
All-cause mortality
The all-cause mortality will be recorded.
Lung transplantation
The lung transplantation will be calculated in each cohort at the end of the trial.
Frequencies of acute exacerbations (AEs)
The frequencies of acute exacerbations (AEs) will be recorded. The diagnostic criteria for acute exacerbation refer to the 2016 international consensus and the 2019 Chinese expert consensus.
Proportion of progressive-free survival
The Proportion of progressive-free survival will be recorded.The disease progression criteria refer to the relevant provisions of the 2022 ATS/ERS/JRS/ALAT Clinical Practice Guidelinefor PPF, including deterioration of respiratory symptoms, physiological evidence of disease progression, and radiological evidence.
6 Six Minute Walk Distance(6MWD)
6MWD will be applied to evaluate the exercise capacity. The higher values indicate the better exercise capacity.
Pulse Oxygen Saturation（SPO2）
Before and after the 6-minute walk test, blood oxygen saturation (SPO2) will be detected through a pulse oximeter monitor.
