Pay attention
Because 不管 means “no matter”, the clause that follows 不管 is going to include phrases such as “how hard you try” or “wherever you go”. Thus, the structure will normally include an interrogative statement.
After 不管, there must be an interrogative statement. It may be expressed by:
1) the interrogative words;
2) the words 多 or 多么 “how much”, which are stated before the predicate.
