Item 4. Changes in Registrant's Certifying Accountants.

     Effective  May 16,  2000,  Merri  Nickerson,  CPA  ("MN"),  resigned as the
independent  accountant for Huading Financial Networks,  Inc., formerly known as
Centrock Incorporated (the "Registrant").  The Registrant did not engage another
independent  accountant to perform its audit for fiscal years ended  December 31
2001 or 2000.  Effective March 6, 2002, Grant Thornton  International ("GT") was
engaged as the principal  independent  accountant.  GT has been engaged to audit
the fiscal  years  ended  December  31,  2001 and 2000.  The  decision to change
auditors was approved by the full board of directors of the Registrant.

     During the Registrant's fiscal year ended December 31, 1999, and the period
from October 20, 1998 to December 31, 1999,  and the  subsequent  interim period
prior to May 16,  2000,  there  were no  disagreements  with MN on any matter of
accounting principles or practices,  financial statement disclosure, or auditing
scope or procedures,  which  disagreements if not resolved to MN 's satisfaction
would  have  caused  it to  make  a  reference  to  the  subject  matter  of the
disagreements in connection with its reports.  During these periods,  there were
no "reportable events" described under Item 304(a)(1)(iv) of Regulation S-B.

     The audit report of MN on the financial  statements of the Registrant as of
and for the fiscal year ended  December 31, 1999 and for the period from October
20, 1998 to December 31, 1998, did not contain any adverse opinion or disclaimer
of opinion, nor were they qualified or modified as to uncertainty,  audit scope,
or accounting principles.

     The Registrant has authorized MN to respond fully to the inquires of GT and
has  requested  that MN provide the  Registrant  with a letter  addressed to the
Securities  and Exchange  Commission  stating  whether she agrees with the above
statements.  A copy of that letter,  dated May 7, 2002, is filed as exhibit 16.1
to this Form 8-K.

     During the  Registrant's  two most recent  fiscal years ended  December 31,
2001 and 2000,  and the  subsequent  interim  period  through March 6, 2002, the
Registrant  did not consult with GT  regarding  any of the matters or events set
forth in Items 304(a)(2)(i) and (ii) of Regulation S-B.

Item 4. Changes in Registrant's Certifying Accountants.

     Effective  May 16,  2000,  Merri  Nickerson,  CPA  ("MN"),  resigned as the
independent  accountant for Huading Financial Networks,  Inc., formerly known as
Centrock Incorporated (the "Registrant").  The Registrant did not engage another
independent  accountant to perform its audit for fiscal years ended  December 31
2001 or 2000.  Effective March 6, 2002, Grant Thornton  International ("GT") was
engaged as the principal  independent  accountant.  GT has been engaged to audit
the fiscal  years  ended  December  31,  2001 and 2000.  The  decision to change
auditors was approved by the full board of directors of the Registrant.

     During the Registrant's fiscal year ended December 31, 1999, and the period
from October 20, 1998 to December 31, 1999,  and the  subsequent  interim period
prior to May 16,  2000,  there  were no  disagreements  with MN on any matter of
accounting principles or practices,  financial statement disclosure, or auditing
scope or procedures,  which  disagreements if not resolved to MN 's satisfaction
would  have  caused  it to  make  a  reference  to  the  subject  matter  of the
disagreements in connection with its reports.  During these periods,  there were
no "reportable events" described under Item 304(a)(1)(iv) of Regulation S-B.

     The audit report of MN on the financial  statements of the Registrant as of
and for the fiscal year ended  December 31, 1999 and for the period from October
20, 1998 to December 31, 1998, did not contain any adverse opinion or disclaimer
of opinion, nor were they qualified or modified as to uncertainty,  audit scope,

     The Registrant has authorized MN to respond fully to the inquires of GT and
