What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The clinical control rate of sputum | Defined as the proportion of patients with the expectoration rate ≥90%. | Day 7 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Time to sputum turn white |  | up to Day 7 | 
| Cough Symptom Score Scale | Cough Symptom Score Scale include Day Cough Symptom Score and Night cough symptom score. In Day Cough Symptom Score, zero means no cough,one means occasionally short cough,two means frequent cough, slightly affecting daily activities,three means frequent coughing seriously affects daily activities;In Night cough symptom score,zero means no cough,one means short-term cough when falling asleep or occasional night cough,two means cough slightly affects night sleep,three means cough seriously affects night sleep. | 0,Day 3, Day 7 | 
| Use of Antibiotic |  | 0,Day 3, Day 7 | 
| Chronic obstructive pulmonary disease Assessment Test |  | 0,Day 3, Day 7 | 
| The Phlegm-heat Syndrome (Tan-re Zheng) scale | The Phlegm-heat Syndrome (Tan-re Zheng) scale include measures of the main symptoms and the secondary symptoms. The main symptom is about the color ，the characteristics and the amount of sputum.Each one includes four levels,0 represents normal，3 represents mild symptom,6 represents moderate symptom,9 represents Severe symptom.The secondary symptoms include Day cough，Night cough，Dry throat thirst，fever，blush，Dry stool，Yellow urine ，Red tongue and pulse.Each one includes different levels.The higher score represents the more meeting The Phlegm-heat Syndrome (Tan-re Zheng) ，the lower score means the opposite. | 0,Day 3, Day 7 | 
| The change value about the volume of sputum after treatment | Monitor the sputum volume everyday and compare changes in sputum volume in the treatment. | 0,Day 3, Day 7 |
