The paper “The 4.2 ka BP event: muLti-proxy from a closed lake in the northern margin of the East Asian summer monsoon” by Xiao et al. shows a good review of palaeoclimate data and reappraisal of palaeoclimate reconstruction around 4.2 BP yrs from data already presented in the same lake. The article is well focused on the topic of special issue and provides a good contribution to the knowledge of the issue.
The authors did a good work in accepting most of the reviewers' suggestions and the article has improved. However, in my opinion some minor problems are still present.

I think that the introduction is still too similar to the paper Xiao et al.2018 (Quaternary International) and it also seems strange that this paper on the some topic is not cited in this work.

Moreover, as far as concerns fig. 5 I agree with Bradley’s suggestion and the connections with HSG seem to me weak.
However, I understand the reply and if the authors prefer to maintain the figure in my opinion it could be useful to enlarge the discussion about this figure providing also a comparison with other more regional records in order to reinforce the interpretation obtained from the lake.

I think that this paper could be accepted for final publication after these minor changes are done.
