-I turned off all background apps
-tested in high performance mode
-I checked the BIOS to see if it was in performance mode
I've tried it many times, but the results are too low. What is the problem ?

I feel you....I got a Yoga 520 with an i7-8550u, and getting ridiculous scores of 399 for multi.
I'm deeply disappointed and can't believe the 320s with the i5-8250u is getting a score of 516, and the 320s is supposed to be even more (thermally) limited tahn the Yoga 520, because of the lower weight and tighter structure, so it makes no sense to me that Lenovo limited the processor to such a degree on the Yoga 520/720 - I couldv'e bought a model with an i7-7500u and get a better performance.

You are getting such a low score because Lenovo has disabled Turbo mode and the CPU like to run around base clock all the time which is 1.6 GHz.
I am using Yoga 720 13 inch model with i5 8250U and using ThrottleStop with undervolting and Turbo enabled, could get 472 in Cinebench Multi Core and 133. CPU throttle fast because of thermal threshold of 98 Celcius in my case, this is the down side of such compact laptops. Cinebench results are attached.
I am planning to use ThrottleStop with Undervolting from now on as I mostly use the laptop with power supply, with battery backup, it will drain battery really fast as without ThrottleStop and Turbo, the laptop need around 1W-15 W normal while 27W under full load during cinebench benchmark. Without it, laptop needs less power.
If you want to use ThrottleStop, be warned that it can destroy your system if you will select wrong setting which may overheat and kill CPU or GPU or both.

Ive actually started using throttlestop shortly after ive replied here, it improved the performance a lot with undervolting, and very high scores on Cinebench, pleased overall so far. Lenovo have really no reason to restrict such a powerful processor, and thats a shame.

My only concern is the maximum power consumption. Max TDP for that processor is 15W yet it is consuming around 25W at full load. I am not sure if this is correct or not because undervolt should reduce power consumption to preserve battery. And 25W is well over max TDP of 15W, it doesn't seems safe. Can you check your min, max and package power consumption in ThrottleStop?
