Has Tesla rival BYD Company gotten too expensive? What’s its correct P/FCF?

Tesla rival BYD Company has done quite well in recent months with a PE of 215 so expensive from that perspective, however can anyone tell what its current accurate P/FCF is? It seems to have quite alot of FCF however problem is that BYD Comp. is listed on different exchanges so when looking at yahoo finance im not sure the financials of its US listings BYDDF and BYDDY are accurate. Probably better to look at its native Hong Kong listing 1211.HK however the problem there is that market cap and price are in HKD while its financials seem to be in CNY (Chinese Yuan).

Anybody can give or calculate the accurate P/FCF for BYD? If you have its original cash flow statement that would probably be best or maybe you have some other source that has currencies converted accurately to determine correct P/FCF. Thanks.
