I noticed a mismatch: the text you supplied discusses vivo’s upcoming X300 series and Pad6 Pro, but the headline you gave is for OPPO (欧珀) Find X9s Pro. Which do you want the article to cover?

• I can write the requested 3–5 paragraph news article about OPPO Find X9s Pro — please confirm and, if possible, provide a source or let me know I should use other reporting.
• Or I can write the article based on the provided ifeng/vivo leak material (vivo X300 Ultra / X300s / Pad6 Pro). If so, I’ll treat the ifeng content as the source.

Reply with your choice and I’ll produce the article in markdown.
