Unfortunately financial and officer/director data for Hong Kong private companies is hidden behind a paywall (see details here under the section Tear Down That Wall: https://webb-site.com/articles/identity2.asp), although at least it is available, as far as it goes, but even then, the Ultimate Beneficial Owner is not public. [This is the situation currently being litigated against Huawei CFO Meng Wanzhou, who it is claimed still controlled a Hong Kong company Skycom (https://dataguru.hk/hkcompany?crno=0644842) behind the scenes].
