Despite a recent price surge, the company's high P/S ratio and declining revenue could lead to a future share price decline. Investors hope for a business turnaround, but without significant improvement, the share price may not be fair value.

Despite declining revenues, Lanzhou Huanghe Enterprise's P/S ratio surpasses industry peers, suggesting investors may be less bearish. However, continued medium-term revenue trends could risk a share price drop and a lower P/S ratio, endangering shareholders and potential investors.
