Despite strong revenue growth, the company's high P/S ratio is concerning. Investors may face disappointment if the P/S ratio falls to match recent growth rates. Without significant medium-term performance improvement, preventing a P/S ratio decline will be tough.

The company's EBIT loss of CN¥46m and negative free cash flow of CN¥97m over the last twelve months raise concerns about its debt levels. The slow rate of revenue growth and 'unfit' balance sheet make the stock risky.

Despite recent revenue growth, the company's high P/S ratio may pose a risk. If revenue growth doesn't outperform the industry, share price could decline, risking investor losses.
