     I, Yanbia Bai, certify that:

     1.   I have reviewed this quarterly report on Form 10-QSB of Cybrdi, Inc.

     2.   Based on my knowledge, this report does not contain any untrue
          statement of a material fact or omit to state a material fact
          necessary to make the statements made, in light of the circumstances
          made, not misleading with respect to the period covered by this

     3.   Based on my knowledge, the financial statements, and other financial
          information included in this report, fairly present in all material

          establishing and maintaining disclosure controls and procedures (as
          defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) and the
          internal control over financial reporting (as defined in Exchange Act
          Rule 13a-15(f) and 15d-15(f) for the issuer and have:

          a.   Designed such disclosure controls and procedures, or caused such
               disclosure controls and procedures to be designed under our
               supervision, to ensure that material information relating to the
               issuer, including its consolidated subsidiaries, is made known to
               us by others within those entities, particularly during the
               period in which this report is being prepared;

          b.   Evaluated the effectiveness of the issuer's disclosure controls
               and procedures and presented in this report our conclusions after

               of the end of the period covered by this report based on such
               evaluation; and

          c.   Disclosed in this report any change in the issuer's internal
               control over financial reporting that occurred during the
               issuer's most recent fiscal quarter (the issuer's fourth fiscal
               quarter in the case of an annual report) that has materially
               affected, or is reasonably likely to materially affect, the
               issuer's internal control over financial reporting; and

     5.   The issuers other certifying officer(s) and I have disclosed, based on
          our most recent evaluation of internal control over financial
          reporting, to the issuer's auditors and the audit committee of the
          issuer's board of directors (or persons performing the equivalent
          functions):

          a.   All significant deficiencies in the design or operation of
               internal control over financial reporting which are reasonably
               likely to adversely affect the issuer's ability to record,
               process, summarize and report financial information; and

          b.   Any fraud, whether or not material, that involves management or
               other employees who have a significant role in the issuer's
               internal control over financial reporting.
