Here's an "english" datasheet for a similar chip: www.stcmcu.com/datasheet/stc/stc-ad-pdf/stc12c5a60s2-english.pdf
can I use this one to program the chip? programmmer
that's a USB/Serial adapter, rather than a device programmer. OTOH, the way I read the datasheet I linked, that PROBABLY is sufficient. (That also means that any other USB/Serial adapter should work, including the one on an Arduino.)
