As far as I know, the funds needed to invest in tea shops mainly depend on the following factors:

1. Store rent

2. Decoration expenses

3. Equipment procurement

4. Procurement of raw materials

5. Personnel salary

6. Working capital

To sum up, opening a 30-square-meter tea shop, The initial investment is roughly required: rent (calculated by half a year)+decoration expenses+equipment procurement+raw material procurement+personnel salary (calculated by three months)+working capital (calculated by three months) =15000-30000+15000-30000+20000-30. 0000-20000+5000-10000 = 60000-100000 yuan.
