Ya jiuhukia same can’t speak English well, especially those from Johor. But I can speak to them in mandarin so no issue. And in recent two years, I noticed those real young mudland chinese in Johor like those below age 20 students can listen and speak English. Oh your brother in law is 58 years old and speak English like primary one standard means I am correct those around 60 and below can’t speak English while those around 60 and above can. It must be due to the education policy switch by Mahathir from English to Malay medium.
