Form S-4 Amendment 2

Questions and Answers about the Proposals for Shareholders
Q: What vote is required to approve the proposals presented at the Meeting?,
page 14

1.     We note your revised disclosures on page 68 regarding the ownership
level of your
       Sponsor and other initial stockholders. Please revise to highlight here
that your Sponsor
       and other initial stockholders own 70.74% of your outstanding shares,
have agreed to vote
       their shares in favor of the Business Combination, and accordingly, the
approval of your
       public shareholders is not needed to approve the Business Combination.

2.       We note that you have deleted portions of your description of the
transaction
         background on page 113. If you meant to move the disclosures to a more
chronological
         order, please move and restore the disclosures accordingly. If you
intended to delete these
         disclosures, please explain why as the disclosures appear to be
important to understanding
         the transaction background.
Venture Report, page 116

3.       We note the statement on page 118 that the information about Xynomic
in the Venture
         Report does not constitute disclosures made by Xynomic or Bison under
this proxy
         statement/prospectus. While it may be acceptable to include qualifying
language
         concerning information in the Venture Report, it is inappropriate to
disclaim responsibility
         for disclosure made in the proxy statement/prospectus, which includes
the Venture
         Report. Please revise to remove this disclaimer.
Liquidity and Capital Resources, page 170

4.       We note that you have revised the disclosure on pages 170-171 to say
that you intend to
         use remaining funds in the Trust Account to identify and evaluate
target businesses, as
         opposed to acquiring Xynomic. Please explain the reason for this
revision.

5.       Please revise Figure 9 on page 187 to also show Grades 4 and 5 or
revise the last
         paragraph on page 187 to disclose each reported SAE in Arm B.
Executive and Director Compensation of Xynomic
Employment Agreements, page 231

6.       You state here and on page 196 in your revised disclosures that Dr.
Zhao's agreement
         provides for non-competition restrictions for 24 months after the term
of his employment,
         but the agreement provisions do not appear to correspond. Please
revise or advise.
Beneficial Ownership of Securities, page 244

7.       We note that your column on the right continues to reflect ownership
assuming 67%
         redemption, even though the maximum permitted redemption has now
decreased to
         29,041 shares. Update the column if applicable or advise. Please also
revise your risk
         factors disclosure to discuss the high insider ownership that will
remain following the
         business combination.

Exhibits

9.       We note your revised 5.1 opinion and refer to our prior comment 7.
Your counsel
         continues to state in the penutlimate paragraph that it relies on the
2017 BVI counsel
         opinion to provide certain of its opinions, even though the opinions
relate to securities of a
         Delaware entity following the domestication transaction. Please file a
revised opinion
         without this reliance or alternatively, further explain why this
assumption is necessary.
         We also note the revised opinion for the units. Please also file a
revised 5.1
         exhibit opining that the units will be your binding obligations, and
also opines on the
         shares of common stock that are part of the units. See Section
II.B.1.f and h of Staff Legal
         Bulletin No. 19 for guidance.
