While only the CCP holds effective power at the national level, there are officially eight minor parties that exist alongside the CCP.[2] Founded before the proclamation of the People's Republic of China, these parties must accept the "leading role" of the CCP as a condition of their continued existence.[3] The relationship between these parties and the CCP has officially been described as "long-term coexistence and mutual supervision, treating each other with full sincerity and sharing weal or woe".[4] According to Human Rights Watch, these parties "play an advisory rather than an oppositional role".[5] The eight minor parties take part in "united front work" and also take part in the political system, but they have no power at a national level.[6][2] The Chinese political system allows for the participation of some members of the eight minor parties and other non-CCP members in the National People's Congress (NPC), but they are vetted by the CCP.[5] According to Aaron Friedberg, these parties' "purpose is to create the illusion of inclusiveness and representation."[7] One of the ways the CCP controls the minor parties is through its United Front Work Department (UFWD), which vets the membership applications and controls who is the leader of these parties.[8] UFWD also keeps the parties in check by preventing them from expanding widely in counties and villages.[8] There is officially a ranking system of the parties; the ranking is based on their "contribution to the new democratic revolution".[9]

Aside from ensuring that leaders are Communist Party loyalists, the UFWD keeps the minor parties small in size and scope by preventing them from operating widely in counties and villages, leaving them unable to amass a broad enough base to claim to represent the Chinese people.
How does the CCP prevent the minority parties from obtaining too many seats and is there a hard cap on how many seats they can get? The cited article says they just prevent them from reaching out to people in counties and villages, but there's no hard cap on the number of seats. Is there any official hard cap or it means that the Chinese government will do whatever it can whenever it feels like the minor parties may become a threat?
