What is the management system of Beijing Taineng Hotel?

Hehe, the hotel where I used to work used Tylenol, but later I switched to software. Taineng's product failure rate is too high, the statements are often uneven, and some inexplicable problems often appear. Later, I couldn't stand it, so my boss changed. At first, it was to save money, but as a result, the money was not saved and there was a lot of trouble. It is best to use the software products of big companies.
