24 bit ADC

[BAS-BLEU]

We need 24 bit low speed adc, i have found HX710B is low cost and 24 bit----but one big problem is it is chines manufaturer.can we use it for weighing scale with stm32f103 or stm8 series MCU reliably

I don't know why this is a problem.
If you can source the IC itself and find the datasheet, you are fine.
It probably has a SPI or I2C interface, and there are plenty of driver examples.

I suppose you know what you are doing.
Designing a proper hardware for a 24-bit ADC and really achieve nearly the accuracy and stability the 24 bit promise is far from easy.

As @Ozone said, why should that be a problem? A microcontroller cannot tell the nationality of external components!

As for any other component, you just need to study its datasheet, and see if what is specified there is compatible with the capabilities of your chosen microcontroller:

As @Ozone suggested, achieving anything like 24-bit accuracy in practice requires very careful, precision analogue design!
