Is it legal for hotels not to receive relatives?

Illegal. According to the enquiry of China Travel Service. Hotels are not allowed to accept relatives from the overlord clause. The so-called "overlord clause" is an unequal format contract, notice, statement, shop notice or industry practice unilaterally formulated by some operators to avoid legal obligations and reduce their own responsibilities, which limits the rights of consumers and seriously infringes on the interests of the masses. The "overlord clause" is illegal.
