anyone that 还是anyone who

anyone who
你说的只能用that,指的是在that和which之间选择,anyone虽然是不定代词,但是他现在指代人,应该用who

只能用that作为定语从句的关系代词的情况
a) 在there be 句型中，只用that，不用which。
b) 在不定代词，如：anything, nothing, the one, all, much, few, any, little等作先行词时，只用that，不用which。
c) 先行词有the only, the very修饰时，只用that。

anything that
anyone who

都可以阿。
