Our pursuit of Yan'an is like a lost child's pursuit of his mother.

I have searched for Yan'an thousands of times in my dreams.

I traced the historical footprints of the Red Army in the Yan'an period, compiled those precious historical materials, and compiled a book that will inspire future generations.

Tips for supplementing sentences: 1. When supplementing sentences, you must locate the relationship between sentences and clarify the internal logical connection between the preceding and following sentences. Pay special attention to related words and summary of rules.

?2. Make it clear whether the supplementary sentence is an introductory sentence that leads to the following, an expansion sentence that connects the previous and the following, or a concluding sentence that summarizes the content.

?3. When writing, you need to consider the unity of the statement object and topic, the rationality of the statement sentence, etc.

?4. Check whether the written content meets the requirements of the question, whether the language is coherent, whether there are any language errors, whether it is concise, etc.
